Abstract
A method for producing arylene sulfide polymer in which a reaction mixture containing at least one polyhalo-substituted aromatic compound, at least one organic amide, at least one alkali metal carboxylate, H.sub.2 S and water in an amount up to 5 weight percent of the total of the reaction mixture components is contacted at polymerization conditions for a time sufficient to produce polymer. In a preferred embodiment, at least one alkali metal carboxylate is present in the reaction mixture.
Claims10
A method for producing polymers comprising:
- (a) contacting at polymerization conditions a reaction mixture consisting essentially of:
- (1) at least one polyhalo-substituted aromatic compound,
- (2) at least one organic amide,
- (3) at least one alkali metal carbonate,
- (4) H.sub.2 S, and
- (5) water in an amount up to 5 weight percent of the total of the other reaction mixture components, and
- (b) maintaining said reaction mixture at polymerization conditions for a time sufficient to produce polymer.
