Abstract
The disclosure is directed to preformed, reactive catalysts, which are the reaction products 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.
Claims16
A preformed, reactive catalyst, capable of crosslinking an alkylene-alkyl acrylate copolymer to a crosslinked product while catalyzing the crosslinking reaction, which is the reaction product of a mixture containing an organo titanate, a polyol having at least two primary hydroxy groups attached to non-adjacent carbon atoms and a monohydric alcohol, said reactive catalyst containing the repeating unit:
- ##STR6## wherein R is a divalent hydrocarbon radical and each R.sup.1 is a monovalent hydrocarbon radical.
