Method of incorporating an additive into a polyamide-poly(arylene ether) composition, composition prepared thereby, and article comprising the composition

摘要

A method of incorporating an additive into a polyamide-poly(arylene ether) composition includes the step of melt blending a polyamide, a poly(arylene ether), and a dispersion comprising a liquid carrier, an unmodified clay, and an additive. Using the dispersion rather than a polymer-based additive masterbatch saves energy. Like a polymer-based masterbatch, the dispersion provides the additive in a diluted form and therefore preserves the masterbatch's advantages of providing more uniform distribution additive in the plastic and avoiding direct handling of additives in the final compounding step.
