Abstract
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.
