Silicone composition which can be crosslinked into elastomers and which comprises crosslinkable polyglycol ethers

摘要

Silicone elastomers exhibiting high breakdown voltage and improved static decay characteristics are prepared from a crosslinkable silicone composition containing an ethylenically unsaturated polyoxyalkylene polyether which becomes chemically bonded into the elastomer during cure.

1. A crosslinkable silicone composition (M) that can be crosslinked to give elastomers, comprising at least one polyglycol ether compound (PE) which has at least one unsaturated group and which can be incorporated by crosslinking, and which comprises structural elements of the formula I
(O—(CH2)v)w—O  (I), in which v is 1, 2, 3, or 4, and w is from 2 to 50, where the content of structural elements of the formula I in the silicone composition (M) is from 0.001 to 0.067% by weight.
