양쪽 작용기성 개시제에 의한 그룹 전이중합(GTP) : ABA 트리블락 공중합체의 쉬운 합성방법

학위논문(석사) - 한국과학기술원 : 화학과, 1988.2, [ iii, 36 p. ]"Living" polymerization of methacrylates and acrylates was achieved over a broad range of polymerization temperatures by using bifunctional initiators in the presence of bifluoride catalysts. The copolymerization of various acrylic monomers with new bifunctional initiators and catalysts was studied. Bifunctional initiators, [1,6-Dimethoxy-2,5-dimethyl-1,5-hexadiene-1,6- diylbis(oxy)]bis[trimethylsilane] and [1,5-Dimethoxy-2,4-dimethyl-1,4- pentadiene-1,5-diylbis(oxy)]bis[trimethylsilane], were presented by silylation of the dianions of corresponding esters. ABA tri-block copolymers were prepared from methyl methacrylate(MMA) and butyl methacrylate(BMA); MMA and allyl methacrylate(AMA): MMA and methyl acrylate(MA); MMA and acrylonitrile(AN); MMA and 2-hydroxyethyl methacrylate(HEMA).한국과학기술원 : 화학과
