Program a kniha abstrakt
Ilavský, Michal ; Dušková, Miroslava
Proceedings of the 44th Microsymposium of Prague Meetings on Macromolecules contain abstracts of 42 lectures and over 100 posters that cover the areas of preparation and chemical modification of polymer gels and networks; gelation and network formation – experiment and theory; gel and network states of matter and gels in life sciences, technology and applications.
Program a kniha abstrakt konference P. M. M. Současné a budoucí trendy polymerních materiálů /23./
Raab, Miroslav ; Kotek, Jiří
Proceedings of the 23th Discussion Conference of Prague Meetings on Macromolecules, covering various aspects of science, technology, economy and ecology of polymeric materials. The conference balanced realistic approaches and visionary perspectives.
Botnací chování poly(N-izopropylmethakrylamidových) a poly(N-isopropylakrylamidových) sítí s náboji ve směsných roztocích voda/ethanol
Alenichev, I. ; Sedláková, Zdeňka ; Ilavský, Michal
Swelling behavior of negatively (ionic comonomer - sodium ethacrylate) and positively (ionic comonomer - (2-crylamidoethyl)trimethylammonium chloride) charged networks of poly(N-isopropylmethacrylamide) (PIPMAm) and poly(N-isopropylacrylamide) (PIPAAm) was investigated in water/ethanol mixtures at room temperature. Strong cononsolvency effect was observed for uncharged and negatively charged gels of both systems.
Nanotechnology as potential method for recycling of PET bottles
Kráčalík, Milan ; Mikešová, Jana ; Pospíšil, L. ; Fortelný, Ivan ; Šimoník, J.
Recycling of PET worldwide is not sufficient. This issue results from decreasing molecular weight due to thermal, mechanical and hydrolytic degradation during multiple processing of polymer. The viscosity (next processability) of material can be increased by preparation of nanocomposites (formation of physical network in the polymer/clay system). The improved processing and utility properties of recycled PET were analyzed by rheology, morphology and tensile tests.
Use of compatibilization in recycling of commingled plastic waste
Starý, Zdeněk ; Kruliš, Zdeněk ; Beneš, Hynek
An efficient compatibilization system based on the combination of styrene-butadiene block copolymer (SBS) with ethylene-propylene random copolymer (EPM) has been developed for polyolefin/polystyrene blends and commingled plastic waste. Efficiency of this system can be further improved by incorporation of N,N´-disubstituted phenylenediamine stabilizer.
Structure characterization of glucanes by 13C NMR spectroscopy
Spěváček, Jiří
The principles of high resolution solid state 13C NMR spectroscopy are explained in this contribution. Some possibilities of this method in the structural characterization of glucans and their derivatives are demonstrated on examples of cellulose, chitin, chitosan and chitin/glucan complexes.
Equations of state for polymers – influence of initial reduction parameters estimate on calculation result
Jůza, Josef
When calculating reduction parameters for equation of state for polymers from pressure – volume - temperature data, the way of calculation of their initial value has some influence discussed in the lecture.
Bases of infrared spectroscopy
Trchová, Miroslava
Basis of molecular vibration spectroscopy, principles of FTIR spectrometer.
Příprava a charakterizace monolitických kolon na principu vtištěných polymerů
Širc, Jakub ; Bosáková, Z. ; Michálek, Jiří ; Guryča, Vilém
By in situ polymerization prepared molecularly imprinted polymer rods were characterized by porosimetry, scanning electron microscopy and by separation of standard hydrophobic solutes and enantiomer pairs.
Hydrofilní polymerní systémy pro kapilární elektroforetické separace
Guryča, Vilém ; Novotný, M. V. ; Michálek, Jiří ; Pacáková, V.
The present work deals with preparations of polymeric stationary phases/coatings for separations of biologically active compounds such as glycoproteins and glycans.
