Two UV curable hyperbrancbend polysiloxanes(I and Ⅲ) containing vinyl and allyl end groups and an UV cationic curable hyperbranehed polymer Ⅱ-Ep with epoxy end groups
were synthesized via the polyhydrosilylation using AB2 type monomers.All hydrosilylation reactions were catalyzed by Pt/C or chlomplatinic acid.Three AB2 type monomers were synthesized via hydrolyzation of functional ehlorosilane prepared by using Grignardeagents.and diehlorosilane.Themolecular structuresofthepolymers were characterized by 1H-
29Si-NMR
FTIR and GPC.and the UV-curing behaviors of polymers in different atmospheres and different photoaeeeleratots were also investigated.
