Abstract
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.
