Abstract
A method for affecting the crystallization of poly(phenylene sulfide), i.e., lowering the melt crystallization temperature or lowering the rate of crystallization of the polymer, in which phenylene sulfide polymer is contacted with polyvalent metal cations in solution, preferably aqueous at a temperature and for a time sufficient to affect the crystallization of the polymer.
