Studies on the Synthesis and Properties of Siloxane Containing Benzoin Ether Group

Abstract

Abstract: Allyl benzoin alkyl ethers (Ⅰ_a,b), r-(benzoin alkyl ether) propylcyclotetrasiloxanes (Ⅱ_a,b), and polysiloxanes containing a pendent benzoin alkyl ether group (Ⅲ_a,b)were synthesized and structurally characterized. These photoinitiators were used for the curing of polymethyl r-(methacry-loxy) propyl siloxane (Ⅳ). All of the organosiloxane photoinitiators show a good compatibility with the photosensitive polysiloxane(Ⅳ). The cyclotetrasiloxane photoinitiators(Ⅱ_a,b) exhibit a higher curing speed.

Key words: Photoinitiator, Benzoin ether, Siloxane, Organosilicon photosensitive polymers
