Process for producing a chloroprene rubber composition, a chloroprene rubber composition, and an adhesive using the same

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a chloroprene rubber composition from which solvent type adhesives excellent in adhesive physical properties and layer separation stability can be produced and which itself is excellent in storage stability.;SOLUTION: In the method for producing the chloroprene rubber composition, chloroprene is emulsion-polymerized in the presence of a rosin acid salt, a polymerization inhibitor is added therein to stop the emulsion polymerization after the polymerization degree of the monomers reaches 50 to 90%, and at least one of specific ethylenic unsaturated sulfonic acid compounds is added to the polymerization-finished polychloroprene latex.;COPYRIGHT: (C)2009,JPO&INPIT
