  • Patent number: 9005476
    Abstract: Polyarylene sulfide/liquid crystal polymer alloys are described as are methods of forming the polyarylene sulfide/liquid crystal polymer alloys. The polyarylene sulfide/liquid crystal polymer alloys are formed according to a melt processing method that includes melt processing a polyarylene sulfide with a reactively functionalized disulfide compound and a liquid crystal polymer in a one or two step process. The reactively functionalized disulfide compound is added in a stoichiometric amount to react with a portion of the polyarylene sulfide. The melt processing forms a polyarylene sulfide/liquid crystal polymer copolymer that is a compatibilizer in the alloy. The polyarylene sulfide/liquid crystal polymer alloys may provide low chlorine content products having excellent strength characteristics.
