<p>A crosslinkable composition comprising (A) a silyl poiym- er, for example an ethylene/vinyl trimethoxy silane copolymer, and (B) a silanol condensation catalyst which is an organic polymer having its polymer chains bridged by dihydrocarbyl tin (IV) containing units of the formula .O.SnR<Sup>1</Sup>R<Sup>2</Sup>O. Also disclosed are aliphatic alpha-olefin/unsaturated carboxyl compound copolymers containing similar dihydrocarbyl tin (IV) bridges. The compositions can be theremoformed into articles, e.g. cable insulation, and crosslinked by water treatment.</p> |
