    Abstract: A continuous fiber composite is described and methods for forming the continuous fiber composite. The continuous fiber composite includes a plurality of unidirectionally aligned continuous fibers embedded within a polyarylene sulfide polymer. The continuous fiber composite includes a very high loading of continuous fibers, for instance greater than about 40% by weight of the continuous fiber composite. The continuous fiber composite is formed by reacting a starting polyarylene sulfide with a reactively functionalized disulfide compound in a melt processing unit. Reaction between the starting polyarylene sulfide and the reactively functionalized disulfide compound leads to formation of a reactively functionalized polyarylene sulfide. Upon embedding of the continuous fibers into the reactively functionalized polyarylene sulfide, the reactivity of the polyarylene sulfide can enhance adhesion between the polyarylene sulfide polymer and the fibers.

    Abstract: A method for injection molding a thermoplastic composition that contains a polyarylene sulfide and an aromatic amide oligomer is provided. Due to the improved crystallization properties imparted by the oligomer, the present inventors have discovered that the thermoplastic composition can be molded at lower temperatures to still achieve the same degree of crystallization. In addition to minimizing the energy requirements for the molding operation, such low mold temperatures may be accomplished using heating mediums that are less corrosive and expensive than some conventional techniques.
