ABSTRACT:
A poly(arylene ether) produced by combining a poly(arylene ether) solution with an antisolvent at a shear rate of greater than 50,000 sec−1. The high shear mixing conditions produce a poly(arylene ether) dispersion in which the poly(arylene ether) solid contains reduced amounts of undesirably fine particles.
