| 摘要 |
A crosslinkable composition comprising (A) a silyl polymer, 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.SnR1R2O. Also disclosed are aliphatic alpha-olefin/unsaturated carboxyl compound copolymers containing similar dihydrocarbyl tin (IV) bridges. The compositions can be thermoformed into articles, e.g. cable insulation, and crosslinked by water treatment.
