摘要： A method for stabilizing a polymeric structure against thermo-oxidative degradation is described. A polymeric core structure is provided with a skin layer that contains a skin resin in which the skin resin at least partially envelops a portion of the core structure. The skin structure then provides a barrier that thereby stabilizes the portion of the structure that is enveloped. The skin resin is made from a treated polyarylene sulfide.

摘要： This invention relates to methods for decreasing the complex viscosity of a polyarylene sulfide polymer melt while maintaining the molecular weight of the polyarylene sulfide with time. This invention also relates to polymer melt compositions comprising a polyarylene sulfide, wherein the complex viscosity of the composition is decreased relative to the complex viscosity of the native polyarylene sulfide measured under the same conditions, and the weight average molecular weight of the polyarylene sulfide is maintained. The methods of decreasing the complex viscosity of a polyarylene sulfide-containing polymer melt, and the polymer melt compositions so obtained, are useful in processes to produce fibers, films, nonwovens, and molded parts from polyarylene sulfides.
