Abstract: The inclusion of an ester of a linear dibasic acid having from 4 to 14 carbon atoms and a branched alcohol having from 4 to 14 carbon atoms in a composition comprising a silyl polymer and an organometallic silanol condensation catalyst, increases the tendency of the composition to crosslink under ambient conditions. The invention includes compositions crosslinkable by the action of water comprising a silyl polymer, a dicarboxylic acid ester and an organometallic silanol condensation catalyst and also processes for the preparation of the compositions.

Abstract: The inclusion of an ester of dipentaerythrital and one or more C.sub.4 to C.sub.8 carboxylic acids in a composition comprising a silyl polymer and an organometallic silanol condensation catalyst, decreases the tendency of the composition to undergo premature crosslinking during the fabrication of articles therefrom. The invention includes compositions crosslinkable by the action of water comprising a silly polymer, the ester and an organometallic silanol condensation catalyst and also processes for the preparation of the compositions.

Abstract: A crosslinkable silyl polymer composition which exhibits a reduced tendency to undergo premature crosslinking during the fabrication of articles therefrom comprises a silyl polymer, an aromatic ester and an organometallic silanol condensation catalyst.

Abstract: A crosslinkable thermoplastic polymeric composition comprising a component inherently adapted for crosslinking by thermal or chemical treatment e.g. a peroxide-containing polyolefin component or a silane-modified polyolefin and a fluorocarbon polymer. The composition can be thermoformed to produce useful articles e.g. cable insulation and the presence of the fluorocarbon polymer (e.g. a copolymer of vinylidene fluoride and hexafluoropropylene) results in the articles having improved surface finish.
