Abstract
A process for preparing arylene sulfide polymers is provided, comprising contacting an initiator compound, a halothiophenol compound, an polar organic compound, and a base. Blends comprising the inventive polymers and polyamides or polyaramides provide improved mechanical properties.
Claims15
A process for producing arylene sulfide polymers comprising:
- contacting an initiator compound, a halothiophenol compound, a polar organic compound, and a base at polymerization conditions;
- wherein said initiator compound is represented by the formula XR(RS).sub.n Y, where R is a divalent hydrocarbon radical selected from the group consisting of arylene, alkyl-substituted arylene, cycloalkyl substituted arylene, and aryl substituted arylene radicals having 6 to 24 carbon atoms;
- n is 1-5;
- X is a halogen selected from the group consisting of fluorine, chlorine, bromine, and iodine;
- and Y is --NH.sub.2 ;
- wherein said halothiophenol is represented by the formula XR'SH, where R' is a divalent hydrocarbon radical selected from the group consisting of arylene, alkyl-substituted arylene, cycloalkyl substituted arylene, and aryl substituted arylene radicals having 6 to 24 carbon atoms and X is a halogen selected from the group consisting of fluorine, chlorine, bromine, and iodine;
- and
- said base is selected from the group consisting of alkali metal hydroxides, alkali metal carbonates, and mixtures thereof.
