    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： 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.

    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 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 and a carboxylic acid sodium salt represented by the general formula: ZCOONa (wherein Z is a C.sub.6 -C.sub.20 aromatic hydrocarbon group or a substituted or unsubstituted pyridyl group ##STR1## where substituents R, which may be the same or different, represent each a C.sub.1 -C.sub.20 organic radical and n is an integer of from 0 to 4), the content of water present in said mixture apart from any water of hydration or crystallization which may be contained in said alkali metal sulfide and carboxylic acid sodium salt being at least 5 moles per mole of said alkali metal sulfide present; thermally dehydrating said alkali metal sulfide 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 so as to produce the intended polymer.

    摘要： In a process in which a poly (arylene sulfide) is synthesized by reacting a dihaloaromatic compound and an alkali metal sulfide in a polar organic solvent, the curing ability of the product polymer is significantly enhanced by introducing a small proportion of a hydroxyl group-containing polyhaloaromatic compound to the reaction mixture when a conversion of at least 60% has been achieved with respect to the dihaloaromatic compound present in the reaction mixture. The product polymer may be advantageously employed in various molding, forming or coating processes to provide the produced articles with increased strengths. The hydroxyl groups introduced into the polymer enable the polymer to be modified, if desired.
