<p>Disclosed herein are high nitrile polymers which have been compounded with a modifier which is a combination of (1) a C12 to C28 saturated aliphatic fatty acid ester of glycerol or sorbitan and (2) a polyoxyethylene sorbitan ester. The amount of modifier used is in the range of from 0.01 to 1.0 percent by weight based on the weight of the nitrile polymer. The compounded polymers exhibit lower malt viscosity and increased melt flow. The modifiers also provide improved clarity, gloss and, in certain instances, articles molded from the compounded nitrile polymer exhibit lower residual monomer levels.</p> |
