Abstract

Abstract: 2-Allyldxy-4-methoxy-bentzophenone (Ⅰ), γ-(4-methoxy-2-oxy-benzophenone) propylhep-tamethylcyclotetrasiloxane (Ⅱ) and polysiloxane containing pendent benzophenone group (Ⅲ) we’re synthesized. These photoinitiators have been used for the photoaddition of polymethylvin-ylsiloxane with 1, 10-dithioldecane. The organosilicone photoinitiators (Ⅱ, Ⅲ) are well compatible with polymethylvinlysiloxane. The effecacy of the photoinitiators has the following order Ⅱ>Ⅲ>Ⅰ.

Key words: photoinitiator, benzophenone, siloxane, photoaddition
