Polyarylene sulfide/liquid crystal polymer alloy and compositions including same

A method of forming a polyarylene sulfide/liquid crystal polymer alloy comprising:

• melt processing a polyarylene sulfide with a reactively functionalized disulfide compound comprising reactive moieties and a fibrous filler, the reactively functionalized disulfide compound being present in a stoichiometric amount to react with only a portion of the polyarylene sulfide to form poiyarylene sulfide endcapped with the reactive moieties of the reactively functionalized disulfide compound;
• combining a liquid crystal polymer with the polyarylene sulfide and the fibrous filler;
• forming a polyarylene sulfide/liquid crystal polymer copolymer that is a compatibilizer in the polyarylene sulfide/liquid crystal polymer alloy, the polyarylene sulfide/liquid crystal polymer alloy including the polyarylene sulfide that does not react with the reactively functionalized disulfide compound, the liquid crystal polymer, and the compatibilizer.
