Abstract
The cold resistance of chloroprene rubber can be improved by blending an ester derived from a specified glycol component and a specified fatty acid component without any adverse effect upon the other physical and chemical properties of the rubber. This ester is not extracted with oily matters such as oil or grease, so that the resulting chloroprene rubber composition hardly exhibits a decrease in cold resistance even after extraction with oily matters.
