Method for improving mechanical properties of addition-crosslinked silicone rubber, addition-crosslinkable silicone rubber composition, and molded article produced therefrom

摘要

A process to improved the mechanical properties of addition crosslinked silicone rubber (I) comprises mixing (I) with an aliphatic unsaturated multiple bonding compound (II). Independent claims are included for: (i) an additional cross-linkable silicone rubber composition consisting of alkenyl functionalized polyorganosiloxane, a Si-H functionalized crosslinking agent, a hydrosilylation catalyst and a compound (III) that liberates (II); and (ii) a molded article produced by crosslinking (I).
