    摘要： A thermoplastic composition for use in a compact camera module is provided. The thermoplastic composition contains a liquid crystalline polymer and a plurality of fibers. The volume average length of the fibers in the thermoplastic composition is selectively controlled according to the present invention so that it is within a certain range, such as from about 80 to about 250 micrometers. The fibers also have a narrow length distribution. That is, at least about 70% by volume of the fibers have a length within a certain range. Through the use of a liquid crystalline polymer and fibers of a certain weight average length and narrow length distribution, the present inventors have discovered that the resulting thermoplastic composition is able to achieve a desirable combination of strength and surface smoothness, which enables it to be uniquely suited for a compact camera module.

    摘要： 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.

    摘要： 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.

    摘要： 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.
