Abstract
A method is provided for producing arylene sulfide polymers employing (1) alkali metal salts of halothiophenols, (2) organic amides, and (3) dihalo aromatic compounds.
Claims8
A method for producing polymers comprising:
- a. contacting an alkali metal salt of a halothiophenol represented by the formula XRSM, where R is a divalent hydrocarbon radical selected from arylene, alkyl-substituted arylene, cycloalkyl-substituted arylene, and aryl-substituted arylene, the number of carbon atoms in said R group being within the range of 6 to about 20;
- X is halogen selected from fluorine, chlorine, bromine, and iodine;
- and M is an alkali metal selected from lithium, sodium, potassium, rubidium, and cesium, said contacting in an organic amide in the presence of a dihalo aromatic compound to form a composition, and
- b. maintaining at least a portion of said composition at polymerization conditions to produce a polymer.
