Abstract
Crosslinkable polymeric compositions comprising (a) a polyolefin elastomer having hydrolysable silane groups, (b) a hydroxyl-terminated polysiloxane, (c) a polyalkoxy silane compatibilizer, and (d) a condensation catalyst. Also described are methods for preparing such crosslinkable polymeric compositions, processes for crosslinking such polymeric compositions, and the resulting crosslinked polymeric compositions themselves. Such compositions can be employed in a variety of articles of manufacture, particularly in the wire and cable industry.

2 more elements
A process comprising:
- (a) combining a polyolefin elastomer having hydrolysable silane groups with a hydroxyl-terminated polysiloxane, a polyalkoxy silane compatibilizer, and a condensation catalyst to thereby form a crosslinkable polymeric composition;
- and
- (b) at least partially crosslinking said polyolefin elastomer and said hydroxyl-terminated polysiloxane thereby forming an at least partially crosslinked polymeric composition.
