摘要： In a process for producing poly (p-phenylenesulfide) from an alkali metal sulfide and a p-dihalobenzene, a product polymer of an advantageously increased molecular weight is obtained by: providing a mixture comprising an alkali metal sulfide, a polar aprotic solvent, a sodium salt of an aliphatic carboxylic acid represented by the general formula: RCOONa (where R is an aliphatic hydrocarbon group having 1-20 carbon atoms), the content of water present in said mixture apart from any water of hydration or crystallization which may be contained in said sulfide and sodium salt being in the range of 5 to 20 moles per mole of said sulfide; thermally dehydrating said sulfide component in said mixture by removing at least part of the water from said mixture; and then contacting the resulting dehydrated mixture with a p-dihalobenzene.

摘要： In a process for preparing a polyarylene sulfide by reacting an alkali metal sulfide and at least one dihaloaromatic compound in an organic amide solvent at an elevated temperature: a highly pure anhydrous alkali metal sulfide reactant having a purity of at least 95% by weight and a content of alkali metal hydrosulfide impurity of not greater than 2% by weight is employed. The water is deliberately added in a proportion of 0.1 to 0.8 moles per each mole of the alkali metal sulfide used in the process. The alkali metal sulfide reactant is charged in a concentration of 2.5 to 5 moles per liter of the reaction mixture. The deliberate addition of water enables one to omit a dehydration stage which has been desirably or rather necessarily effected to obtain a satisfactory polymer product where a hydrous alkali metal sulfide reactant is employed. The improved process of the invention provides a highly pure polyarylene sulfide product having a relatively increased molecular weight and a decreased content of by-product oligomers.

摘要： A poly(phenylene sulfide) material containing predominantly para-phenylene sulfide structural units and having a melt viscosity of at least 5 poises (at 300.degree. C.) may be treated or reacted with an alkali metal sulfide and/or hydrosulfide in a polar aprotic solvent at a relatively low temperature in the range of 150.degree.-230.degree. C. so as to introduce an increased amount of reactive thiolate or thiol end groups to the polymer molecule and hence to enhance the reactivity of the polymer material. The thus modified and highly reactive poly(phenylene sulfide) material exhibits an improved compatibility with other polymers and is expected to be useful in preparation of polymer alloys of improved or modified physical and chemical properties.

摘要： A polyarylene sulfide having a low content of electrolytic ions is economically recovered from a mixture consisting mainly of polyarylene sulfide and an alkali metal halide which mixture is obtained by reacting a polyhalogenated aromatic compound and an alkali metal sulfide containing water in an organic polar solvent, by dehydrating the mixture by distillation, mixing the dehydrated mixture with a solvent which is a poor solvent for both polyarylene sulfide and alkali metal halide and which is soluble in the organic polar solvent to prepare a slurry consisting essentially of the polyarylene sulfide and the alkali metal halide, subjecting the slurry to solid-liquid separation, washing the resultant cake with the poor solvent, drying the cake, adding water to the cake to wash away the alkali metal halide through dissolution, and subjecting the slurry to solid-liquid separation to recover polyarylene sulfide. Such a polyarylene sulfide is particularly useful for use in electronic and electric components and molded articles such as films, sheets and fibers.

摘要： There are disclosed a class of halogen-ended polyalkylene glycols and halogen-ended polyolefins (II) which are copolymerizable with polyarylene sulfides or sulfone-based polymers. These halogen-ended polymers may be readily copolymerized with polyarylene sulfides or sulfone-based polymers to provide polyphenylene sulfide copolymers (I) exhibiting increased crystallization speeds. These high crystallization speeds enable the copolymers to be molded in a low-temperature mold, for example, at 100.degree. C. or less, while providing fully crystallized moldings having excellent heat resistance properties.
