Abstract
The disclosure of this application is directed to a composition based on an alkylene-alkyl acrylate copolymer, a polyhydric alcohol and an organio titanate, the cure rate of which can be retarded by the addition thereto of a molecular sieve. The composition disclosed can be extruded about wire and cables providing protective coatings thereon.

A crosslinkable composition comprising an alkylene-alkyl acrylate copolymer, a primary, polyhydric alcohol wherein primary hydroxyl groups are attached to non-adjacent carbon atoms in an amount sufficient to crosslink said copolymer, an organo titanate in an amount sufficient to catalyze the crosslinking reaction between the primary, polyhydric alcohol and the alkylene-alkyl acrylate copolymer and a molecular sieve in an amount sufficient to retard the crosslinking reaction.
A crosslinkable composition comprising an alkylene-alkyl acrylate copolymer, a primary, polyhydric alcohol wherein primary hydroxyl groups are attached to non-adjacent carbon atoms in an amount of about 0.1 to about 10 percent by weight, an organo titanate in an amount of about 0.1 to about 10 percent by weight and a molecular sieve in an amount of about 0.1 to about 5 percent by weight, wherein amounts are based on the weight of said copolymer.
A process of retarding the crosslinking of a composition containing an alkylene-alkyl acrylate copolymer, a primary, polyhydric alcohol and an organo titanate which comprises adding thereto a molecular sieve in an amount of about 0.1 to about 5 percent by weight based on the weight of the said alkylene-alkyl acrylate copolymer.
A crosslinkable coposition comprising an alkylene-alkyl acrylate copolymer, a crosslinking polyol, in an amount sufficient to crosslink said copolymer, an organo titanate in an amount sufficient to catalyze the crosslinking reaction between said polyol and said copolymer and a molecular sieve in an amount sufficient to retard the crosslinking reaction.
An additive, suitable for crosslinking an alkylene-alkyl acrylate copolymer at elevated temperatures, comprising a polyol capable of crosslinking an alkylene-alkyl acrylate copolymer, an organo titanate catalyst and a molecular sieve.
