Under existing of the metal catalyst which designates carbene as the base the catalyst of the silicone composition and this type which can build a bridge to elastomer by hidoroshiriru conversion

摘要

This invention, being the silicone composition, at least the poly- Organo polysiloxane of 1 where it possesses unsaturated bond kinds by (A), the poly- Organo hydro polysiloxane of 1 kinds using (B) at least, it builds a bridge desirably to elastomer the carbene based metal kind of catalyst which is stipulated in claim 1 (C) to hidoroshiriru making convert under existing, profit, at the same time, it regards those which at least the prohibition medicine of the said hidoroshiriru conversion reaction of 1 kinds include (D) as option.
