ABSTRACT:
Alkali metal aminoalkanoate is prepared by contacting in the presence of an alkali metal carboxylate a reaction mixture in which there is at least one alkali metal hydroxide, at least one lactam, and water. Arylene sulfide polymer is prepared by contacting at polymerization conditions a reaction mixture that contains at least one alkali metal aminoalkanoate prepared as described above; at least one polyhalo-substituted aromatic compound; at least one organic amide as solvent and H.sub.2 S. In an embodiment of the polymerization the organic amide used as solvent can be the same as the lactam from which the alkali metal aminoalkanoate was produced.
