Abstract
A boron-containing nucleating agent is provided for use with a polyarylene sulfide. The boron-containing nucleating agent can have low crystallinity, a small particle size, and a large specific surface area. By selectively controlling certain aspects of the nucleating agent, the crystallization properties of a thermoplastic composition including the nucleating agent and a polyarylene sulfide can be significantly improved. For instance, the recrystallization temperature can be increased, which can allow the 'cooling time' during a molding cycle to be substantially reduced. Through use of the boron-containing nucleating agent the recrystallization temperature can be greater than about 231° C.
