Abstract

Curable blends of chloroprene polymers are obtained by modification with ethylene/carbon monoxide or sulfur dioxide copolymers containing an additional softening copolymerizable comonomer such as vinyl esters, alkyl acrylates and methacrylates, alkyl vinyl ether, acrylonitrile, methacrylonitrile etc. Modification with the ethylene copolymers results in improved processing, increased resistance to ozone and reduced cost.
