A PROCESS FOR MINIMIZING RESIDUAL FREE HYDRAZINE IN POLYMER LATICES

摘要

This invention relates to a process for minimizing or reducing the amount of residual free hydrazine in polymer latices. The process is particularly useful in the manufacture of hydrogenated nitrile rubber which is resistant to oxidative degradation at high temperatures, as well as resistant to corrosive environments such as acid environments. Nitrile rubbers are useful in the manufacture of fan belts, seals, gaskets, and hoses in increasingly small and hot-running car engines.
