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.

摘要： An improved process for forming polyarylene sulfide fibers is provided. The process comprises forming at least one fiber from a polymer melt comprising a polyarylene sulfide and at least one tin additive comprising a branched tin(II) carboxylate. Using such a melt, the fiber forming continuity is improved compared to that of the native polyarylene sulfide melt processed under the same conditions.

摘要： Disclosed is a process for making polyolefin pellet products that contain at least one unreacted free radical generator which, when heated, undergo chemical degradation producing a low viscosity polymer. The process includes contacting the polyolefin pellet with the at least one free radical generator to coat the pellet, and contacting the coated pellets and at least one unreacted free radical generator at an elevated temperature and for a period of time sufficient for the free radical initiator to soak into the interior of the pellets. The process of the invention enables the production of polyolefin pellets having any desired amount of free radical generator and therefore, production of a desired viscosity, and improves the processability of the polyolefin pellet at customer fabrication facilities to thereby provide superior quality final articles.
