Abstract
In the novel hydrosilylation curing system, derived from an α,ω-bis(2,4,6,8-tetramethylcyclotetrasiloxan-2-yl) carbon chain crosslinker 1 and allyl-group-end-blocked oligomer 2, effervescence phenomena during curing were examined. We found that the main component of the gas formed was propylene when 1 and 2 were heated in the presence of H2PtCl6 for cure and that the amount of the gas was largely dependent on the structure of allyl functionality; in the system with allyl carbonate or allyl ester gas genaration was very distinctive and propylene formation was dominant well over the normal hydrosilylation.
