摘    要:同线型聚硅氧烷聚合物相比,超支化聚硅氧烷聚合物具有低粘度、高反应活性和良好的相容性等特点,其中以制备超支化的聚硅氧烷基硅氧烷和聚烷氧基硅氧烷为主.对于超支化聚硅氧烷主要是以ABx(X=2~6)(其中A为双键,B为硅氢键)型单体为原料,在氯铂酸或Pt/C的催化下,通过硅氢加成反应一步制备,最终聚合物的端基(B)为硅氢键,而双键则完全反应,此外也可通过含不同数目烷氧基硅烷的水解缩合制备超支化聚硅氧烷.

关 键 词:超支化聚合物  紫外光固化  聚硅氧烷

Abstract:Two UV curable hyperbranchend polysiloxanes(Ⅰ and Ⅲ) containing vinyl and allyl end groups and an UV cationic curable hyperbranched polymer Ⅱ-Ep with epoxy end groups,were synthesized via the polyhydrosilylation using AB_2 type monomers.All hydrosilylation reactions were catalyzed by(Pt/C) or chloroplatinic acid.Three AB_2 type monomers were synthesized via hydrolyzation of functional chlorosilane prepared by using Grignardeagents,and dichlorosilane.The molecular structures of the polymers were characterized by()~1H-,()~(29)Si-NMR,FTIR and GPC,and the UV-curing behaviors of polymers in different atmospheres and different photoaccelerators were also investigated.
Keywords:Hyperbranched Polymer   UV curing   Polysiloxane
