遊離基乳化重合のショートストップのためのニトロソアミン阻害性組成物
Document Type and Number:
Japanese Patent JP4846897
Kind Code:
B2
Abstract:
The present invention is a composition for and a method of shortstopping free radical emulsion polymerizations that inhibits the formation of nitrosamines. The composition comprises nitrosamine inhibitors in combination with conventional alkylhydroxylamine shortstoppers. Such nitrosamine inhibitors are based on primary amines, amine-containing polymers, pyrroles, hydroquinones, certain phenols, ascorbic acid, and other well-known nitrosation inhibitors; they may be used individually or as a blend. The compositions are targeted for applications in the emulsion processes for producing rubber latexes and the preparation of rubber products thereafter.
