Description
  • Amfifilní polymerní sítě obsahující 41 a 67 mol % HEMA byly připraveny jednostupňovou syntézou z kationtového kopolymeru IB a IDI. PHEMA-PIB síť obsahující 43 mol % HEMA byla připravena radikálovou kopolymerizací PIB(MA)n s HEMA užitím postupné syntézy. Výsledné PHEMA-PIB sítě byly charakterizovány 13C NMR spektroskopií v pevném stavu a DSC. Amfifilní povaha finálních síťí byla prokázána botnáním jak ve vodě tak v n-heptanu. Předběžné biologické testy potvrdily, že PHEMA-PIB hydrogely mohou mít bilologické uplatnění. (cs)
  • Amphiphilic polymer networks containing 41 and 67 mol % HEMA have been prepared by a one-pot synthesis from a cationic copolymer of IB and IDI. PHEMA-PIB network containing 43 mol % HEMA was also prepared by radical copolymerization of PIB(MA)n with HEMA using sequential synthesis. The resulting PHEMA-PIB networks were characterized by solid state 13C NMR spectroscopy and by DSC. An amphiphilic nature of the resulting networks was proved by swelling in both water and n-heptane. Preliminary biological tests of PHEMA-PIB hydrogels confirmed that they can be useful for biomedical applications.
