Abstract
A method for accelerating the curing of a polyarylene sulfide. The polyarylene sulfide is blended with a cure accelerator to form a mixture where the weight percentage of accelerator is between 0.2% and 15.0% of the total weight of the blend. The mixture is cured at 320° C. or above for at least 20 minutes. The cure accelerator is a compound selected from the group consisting of ionomers, hindered phenols, polyhydric alcohols, polycarboxylates, and mixtures of the foregoing.
Claims2
A method for accelerating the curing of a polyarylene sulfide comprising the steps of (i) blending the polyarylene sulfide with a cure accelerator to form a mixture where the weight percentage of accelerator is between 0.2% and 15.0% of the total weight of the blend, and (ii) curing the mixture at 320° C. or above for at least 20 minutes;
- wherein the cure accelerator is a polyhydric alcohol, and the polyhydric alcohol is cyclodextrin, D-mannose, glucose, galactose, sucrose, fructose, xylose, arabinose, D-arabitol, or L-arabitol.
A method for accelerating the curing of a polyarylene sulfide comprising the steps of (i) blending the polyarylene sulfide with a cure accelerator to form a mixture where the weight percentage of accelerator is between 0.2% and 15.0% of the total weight of the blend, and (ii) curing the mixture at 320° C. or above for at least 20 minutes;
- wherein the cure accelerator is a polyhydric alcohol, and the polyhydric alcohol is hexane-1,2,6-triol.
