Telekelikus és blokk-kopolimerek = Telechelic and block copolymers

AB, A2B, A1A2B, A2B2 es A3B3 (AB)3 tipusu (A=poliizobutilen, B=poli(metil-vinil-eter) ) amfifilikus blokk-kopolimereket allitottunk elő es megvizsgaltuk az architectura hatasat a vizes oldatban lejatszodo micellakepződesre. Fenyszoras meresekből az AB, A2B2, A3B3, es (AB)3 blokk-kopolimerek eseteben vizes oldatban vezikulak kepződeset valoszinűsitettuk. Megallapitottuk, hogy a csillag alaku blokk-kopolimerekből kepződott micellak aggregacios szama es hidrodinamikai sugara a hőmerseklettől fuggetlen, mig a linearis AB blokk-kopolimerből kepződott micellak eseteben jelentős novekedes tapasztalhato. Glukoz-, amino-, bisz(imidazolil-1-karboxilat)-, hidroxil-, epoxid-, aldehid- es karboxil-tekelikus polimereket szintetizaltunk. A polimerek szerkezetet NMR es MALDI-TOF MS modszerekkel bizonyitottuk es vizsgaltuk a szarmazekok tomegspektrometias viselkedeset. Megvalositottuk az nbutil-vinil-eter polimerizaciojat alan inicialo rendszerek alkalmazasaval is. Biologiailag lebonthato politejsav-TDI-poli(etilen-glikol) es politejsav-TDI-poli(propilen-glikol) blokk- es/vagy kopolimereket allitottunk elő. A kopolimerek mechanikai tulajdonsagait vizsgalatok alapjan arra kovetkeztettunk, hogy a kopolimerzacio kemiai korulmenyei es a mechanikai tulajdonsagok kozott szoros kapcsolat van. Az előallitott kopolimerekből foliakat keszitettunk es ezek fizikai tulajdonsagait a kereskedelemben kaphato PVC es LDPE foliak mechanikai tulajdonsagaival hasonlitottuk ossze. | AB, A2B, A1A2B, A2B2 and A3B3 (where, A=polyisobutylene, B=poly(methyl vinyl ether)) type block copolymers were synthesized and the effect of their structure on the micelle formation in aqueous media were studied. According to light scattering studies in the case of AB, A2B2, A3B3 and (AB)3 block copolymers the formation of vesicules was confirmed. It was also found that the aggregation number and hydrodynamic radius of the micelles formed from star shaped block copolymers were independent of the temperature, while in the case of micelles formed from linear blocks a significant increase can be observed. Glucose-, amino-, bis(imidazolyl-carboxylate)-, hydroxil-, epoxy-aldehyde-, and carboxyl-telechelic polymers were prepared. The structures of the polymers were confirmed by NMR and MALDI-TOF MS methods. These polymers under mass spectrometric conditions were investigated and phenomena arising in the mass spectrometer were interpreted. The polymerisation of nbutyl-vinyl-ether using the new AlCl3/LiAlH4 initiator systems was also elaborated. The synthesis of biologically degradable poly(lactic acid)-TDI-poly(ethylene glycol) and poly(lactic acid)-TDI-poly(propylene glycol) block and/or copolymers was achieved. A strong connection was found between the chemical conditions of the copolymerization and the observed mechanical properties. The copolymers were converted into foils and their properties were compared to that of the commercially available PVC and LDPE foils.
