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.

    摘要: According to this invention, improved results in terms of molecular weight and percent yield of aromatic sulfide/sulfone polymers are achieved by the employment of a low level modifying agent within a specific range in the polymerization reaction mixture. The modifying agent employed is a salt of an amino carboxylic acid. The salt can be employed as an already existing salt of an amino carboxylic acid or can be formed in situ by employing either an amino carboxylic acid and a base; or a lactam and a base.

    摘要: A method for removing oligomers and non-polymeric impurities from poly(arylene sulfide) polymers and producing the polymers in easily recoverable granular form is provided in which a poly(arylene sulfide) polymer associated with oligomers and non-polymeric impurities is contacted with a solvent, water, and optionally, a base, at a sufficient temperature to substantially dissolve the polymer, oligomers and impurities; then the solution is cooled to a temperature at which the poly(arylene sulfide) precipitates while oligomers and impurities remain in solution, then the precipitated polymer is separated from the solution containing the oligomers and impurities. A polymer product produced by this method is also disclosed.
