Abstract
The disclosure is directed to a preformed, reactive catalyst, which is the reaction product of a mixture containing an organo titanate, a polyol and a monohydric alcohol. These catalysts can be admixed with alkylene-alkyl acrylate copolymers to provide compositions which can be extruded about electrical wires and cables and cured, at improved cure rates, to crosslinked products characterized by improved physical properties.
Claims17
A curable composition comprising an alkylene-alkyl acrylate copolymer, and in an amount sufficient to cure said copolymer to a crosslinked product, a preformed, reactive catalyst which is the reaction product of an organo titanate, a diol having two primary hydroxy groups attached to non-adjacent carbon atoms and a monohydric alcohol.
A curable composition comprising an alkylene-alkyl acrylate copolymer and a preformed, organo titanate containing the repeating unit:
- ##STR5## wherein R is a divalent hydrocarbon radical and R.sup.1 is a monovalent hydrocarbon radical, in an amount sufficient to cure said copolymer to a crosslinked product.
