ABSTRACT:
A method of precipitating a poly(arylene ether) includes 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.
