Composites of fibrous reinforcing agent in air cured poly (arylene sulfide) matrix and production thereof.

摘要

Polymeric composites are provided in which long or continuous fibrous reinforcing agent is surrounded by a matrix of poly(arylene sulfide) prepared as an air curable, linear polymer having a melt flow in the range of about 20 g/10 min to about 30,000 g/10 min and subsequently air cured to reduce the melt flow to 1 percent to 80 percent of the uncured value and within a range of about 1 g/10 min to about 500 g/10 min. Methods are also provided for producing composites by preparing air curable, linear poly(arylene sulfide) which is (a) air cured to reduce melt flow and combined with long or continuous fibrous reinforcing agent or (b) combined with long or continuous fibrous reinforcing agent and then air cured to reduce melt flow.
