    摘要： In a first embodiment, arylene sulfide resins are provided by contacting, in a polymerization mixture, during a polymerization process, reactants comprising: an alkali metal sulfide, an organic amide, an alkali metal carboxylate, water and a monomer source which comprises at least one dihaloaromatic compound. The amount of alkali metal carboxylate present during the polymerization process ranges from about 0.01 to about 0.03 mole per each mole of sulfur present in the resulting arylene sulfide resin. The total amount of water present during the polymerization process ranges from about 1.02 to about 2.1 moles per each mole of sulfur present in the resulting arylene sulfide resin.In a second embodiment, arylene sulfide resins are provided by contacting, in a polymerization mixture, during a polymerization process, reactants comprising: an alkali metal sulfide, an organic amide, an alkali metal carboxylate, water and a monomer source which comprises a mixture of at least one dihaloaromatic compound and at least one polyhaloaromatic compound having more than two halogen substituents per molecule. The ranges of the amount of alkali metal carboxylate present during the polymerization process and the total amount of water present during the polymerization process are identical to those amounts disclosed in the first embodiment. The amount of polyhaloaromatic compound initially present ranges from about 0.0001 to about 0.01 mole per each mole of dihaloaromatic compound present prior to the initiation of the polymerization process.
