For the synthesis of phenyl-vinyl-based polysiloxane resins, novel cross-linking agents containing silicon-hydride such as linear hydrosiloxane oligomers have been discovered via hydrosilylation reaction. Phenyl-vinyl-based oligosiloxanes were synthesized from the reaction of diphenylsilanediol and vinyltrimethoxysilane through a nonhydrolytic sol-gel condensation. linear hydrosiloxane oligomers containing Si-H moiety were obtained from the reaction of dichlorodimethylsilane and dichlorophenylsilane. Dimethylchlorosilane was used as a ending group for the linear hydrosiloxane oligomers. The reaction of phenyl-vinyl-based oligosiloxanes and linear hydrosiloxane oligomers in the present of Pt catalyst was carried out for the synthesis of polysiloxane resins. The prepared phenyl-vinyl-based polysiloxane resins showed a good refractive index, high hardness, and great transmittance. The comparison to previously known phenyltris(dimethylsiloxy)silane as a cross-linking agent has been reported. This research was financially supported by the Ministry of Education (MOE) and National Research Foundation of Korea(NRF) through the Human Resource Training Project for Regional Innovation .
