Abstract
Abstract Compositions of relatively stable polymers of an olefinic monomer and an unsaturated silane; and an organo titanate, wherein a readily hydrolyzable group of the titanate ester exchanges with one ester group of the silane moieties of the stable polymers to provide readily water-curable polymers which are useful as extrudates about wires and cables.

Claim 1
Independent Claim
159 words
A composition of matter comprising a preformed thermoplastic polymer of at least one olefinic monomer and at least one unsaturated silane, said polymer having pendant silane moieties of the formula: ##STR8## wherein R is a straight chain hydrocarbon radical having a minimum of 4 carbon atoms, a branched chain hydrocarbon radical or a hydrocarbon radical bonded to the oxygen atom through a non-terminal carbon atom, having a minimum of 3 carbon atoms, each V is a hydrocarbon radical having 1 to 18 carbon atoms inclusive or an --OR radical wherein R is as previously defined; and an organo titanate of the formula: ##STR9## wherein R 1 is methyl, ethyl or propyl and R 2 , R 3 and R 4 are hydrocarbon radicals having 1 to 18 carbon atoms inclusive; wherein said organo titanate is present in an amount sufficient to ester exchange at least one ester group of the titanate for one ester group of the silane moieties.
Claim 2
Dependent Claim
