POLY(ARYLENE ETHER) PROCESS AND COMPOSITION |
摘要 |
A method of purifying a polymerization reaction mixture containing a poly(arylene ether) is described. The method uses multiple separations of organic and aqueous phases to achieve rapid and efficient removal of polymerization catalyst metal from the poly(arylene ether). When combined with particular precipitation conditions, the method produces a poly(arylene ether) having an improved combination of particle size distribution and low catalyst metal concentration.
