  • Higher molecular weight arylene sulfide resin and process for its preparation
    Patent number: 5110901
    Abstract: 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.
