A process for preparing arylene sulfide polymers which comprises the steps of contacting at least one first alkali metal aminoalkanoate with a molar excess relative to the aminoalkanoate of hydrogen sulfide in an enclosed reaction vessel under reaction conditions of time and temperature sufficient to react the hydrogen sulfide with the first alkali metal aminoalkanoate to produce alkali metal bisulfide and thereby form a first reaction product comprising hydrogen sulfide, alkali metal bisulfide, water and lactam, venting the enclosed reaction vessel to remove hydrogen sulfide present in the first reaction product, contacting the alkali metal bisulfide with at least one second alkali metal aminoalkanoate under reaction conditions of time and temperature sufficient to produce a second reaction product comprising water, lactam and a polymerizable complex of the second alkali metal aminoalkanoate and the alkali metal bisulfide, dehydrating the second reaction product, contacting the dehydrated second reaction product with at least one dihaloaromatic compound to form a polymerization mixture, and subjecting the polymerization mixture to polymerization conditions of time and temperature sufficient to produce the arylene sulfide polymer.
