Abstract:
1. A process for making an elastomeric article, the process comprising: a) preparing a compounded carboxylated nitrile-butadiene terpolymer latex formulation containing, in terms of parts per 100 dry parts of rubber consisting of the carboxylated nitrile-butadiene terpolymer, between 0-1.5 parts of an alkali agent that provides monovalent ions and 0.5-1.5 parts of zinc oxide wherein the total combined amount of the alkali agent and zinc oxide is greater than 1.0 part per 100 dry parts of rubber, a stabilizer and, one or more accelerator from a group including a guanidine, dithiocarbamate, and optionally a thiazole compound, and adjusting the pH of the formulation to about 8.5 or higher; b) dipping a former into said compounded carboxylated nitrile-butadiene terpolymer latex formulation rubber composition; and c) curing said compounded nitrile-butadiene terpolymer latex formulation rubber to form said elastomeric article.
