23rd Discussion Conference
Prague, 26 - 30 July 2005,23rd Discussion Conference
Prague, 26 - 30 June 2005



This conference will be an exception in the PMM series. Rather than concentrating on a particular branch of polymer science, the aim is to evaluate the present situation of various classes of polymeric materials, and consider their future development. Many aspects of science, technology, economy and ecology will be presented and discussed in a manner that balances realistic approaches and visionary perspectives.


The following topics indicate the scope of the conference proceedings but do not limit it:


All sessions will be held in the Institute of Macromolecular Chemistry of the Academy of Sciences of the Czech Republic, Praha 6, Heyrovského nám. 2.

The scientific programme consists of invited main lectures of 30 min and additional 10 min for discussion, special lectures of 15 min and additional 5 min for discussion, two panel discussions, and two poster sessions.


English is the working language of the Conference; no translation will be provided. All materials for publication must be submitted in English.


Data-Video-Projector (XGA) connected to a local PC will be available. Following media can be used for transfer of data: FDD 3.5", CD, DVD-R, USB-Flash. Other supported inputs are via: PC MCIA, IEEE 1394 ports, 4-in-1 Card Reader-Multimedia Card, Secure Digital, Memory Stick, Smart Media, or from VHS. No connection of private notebooks or laptops will be allowed.

In addition, an overhead projector will be available.

Sightseeing in Prague with gala dinner

The excursion starts on Wednesday, June 29, 2 pm at the lecture hall of the Institute, along with a short introductory lecture. Buses will bring participants to several interesting places, starting with Strahov monastery, which boasts of a famous library of books dating back to the 10th century and decorative murals on the ceilings of the Philosophical Hall. After that, it is possible to view the hundred towers of Prague from the Strahov terrace, and to listen to the carillon of the nearby Loreta bell tower.

The next stop will be at the Royal Garden of the Prague Castle, which is highlighted by a Renaissance summer house and so-called 'singing fountain'. Then the participants will be taken to Troja on the outskirts of Prague, where it is also possible to admire a panorama of the city. Nearby is the Botanical Garden, with its tropical greenhouse 'Fata Morgana', which will be included in the sightseeing tour.

The excursion will end in the very centre of Prague, where a gala dinner will be served in one of the historic palaces of Prague. Live music will accompany the service of the meal, in a beautiful setting. As the evening will not have a strict end, and the location is convenient, no further transportation will be provided past this point.

Please book for the excursion using the Registration Form (admission by tickets only). Price: 70 EUR (extra fee).

Accompanying Persons Programme

Guided accompanying persons programme will be provided from Monday through Thursday, depending on interest at the registration desk. Newly, there is NO registration fee for accompanying persons in contrast to what was stated in our 1st circular (300 EUR). The reason is the major change in organization of the accompanying person programme. Instead of pre-arranged full-time schedule for all meeting days as planned previously, the EKU Congress Agency information desk will be open throughout the whole meeting. The participants will have the choice of various excursions to the City of Prague and around Prague with individual on-site reservation. More extensive info, booklets, brochures, maps etc. will be available too in the EKU stand located at the conference site (Institute of Macromolecular Chemistry, Heyrovského náměstí 2).



Final registration

Any person wishing to attend the Conference (including speakers) must submit the enclosed Registration Form to the P.M.M. Secretariat by 15 April 2005.

The Registration Form (unless submitted using the WWW form) should be completed in three copies: any item not filled in means that the particular reservation is not requested. Please return the white and green copies and keep the yellow one; the receipt of your final registration will be confirmed on the green copy sent back to you. The confirmation of Registration Form means only that your registration is accepted; it is not a receipt of payment (see Remittance of fees).

Please note that the title of any contribution should be definitive and identical with the abstract heading (see p. 11).

The abstract does not replace the final registration. Registration Form is also available at https://www.imc.cas.cz/sympo/r23dc.htm

Magic on the outskirts of Prague ...
at the beginning of the 23rd Discussion Conference

The opening reception of the 23rd Discussion Conference will be organized on the premises of the Royal Summer House (known as Star House) located in the close vicinity of the Institute.

In 1555, the Archduke Ferdinand of Tyrolia, second son of the Emperor Ferdinand I, ordered the construction of a Renaissance summer house according to his own design. To assist in the realization of this building he appointed top Italian architects Giovanni Campioni and Avostalis del Pambio. Those masters also decorated the ground floor of the building with stucco reliefs.

The 16th century was a flourishing period for so-called secret sciences and secret societies. This is definitely expressed in the geometry of the building, as the plan is a perfect six-point star shape inside a diameter of sixty feet. Such a star could symbolize two interposed triangles; in other words, an architectonic realization of the Emerald Table of Hermes Trismegistus

The horizontal profile of the structure also has philosophical significance. The four levels could each be understood as the representation of the four elements described in ancient Greek wisdom: Earth, Water, Air and Fire. The ground floor is definitely the most beautiful because of the well-preserved decoration; the first floor is kind of a labyrinth, as it is not so easy to exit as it is to enter! The top floor is no less interesting - it presumably contains visible traces of some 16th century initiation rites. Indeed, the original Renaissance floor tiles still show that the room was divided into red and blue halves on an east-west axis. In this space, one could imagine that a novice would be required to cross this division line as part of its initiation. However, there are no written records of this ceremony; after all, it should be kept a secret, right? In any regard, one's imagination has freedom to develop its own scenes.

The magical atmosphere of the Summer House also inspired the French Surrealist Andre Breton to devote a poem in its honor. A part of it is now engraved in a big stone located at the entrance. More recently, a Chinese visitor remarked that the sharp points of the building can also have the effect of removing negative energy from the inner space. You may also notice the peculiar stanchions placed a meter apart from each of the points: the same visitor considered that they may serve to scatter the offensive fields of energy further, thus avoiding possible harm to passers-by. Of course, scientific minds of today can enjoy these speculations as part of a Renaissance fairy tale. But the special feeling of being inside a star, as it were, remains even after 450 years of its existence.

So, be sure to reserve this particular Sunday afternoon and join us for the opening reception party of the 23rd Discussion Conference. Please gather at 18:00 pm at the entrance of the Institute, after which we will walk together to the Star House (5 min).
