SULFUR-MODIFIED CHLOROPRENE POLYMER COMPOSITION AND ITS PRODUCTION

摘要

PURPOSE: To provide a sulfur-modified chloroprene polymer compsn. greatly improved in ozone resistance and a process for producing the same. CONSTITUTION: The compsn. contains a sulfur-modified chloroprene polymer and anα,β-unsatd. carboxylic ester polymer. The process is characterized in that a sulfur-modified chloroprene polymer latex is mixed with anα,β-unsatd. carboxylic ester polymer emulsion.
