In the pre-curing of particulate poly(arylene sulfide) by contact with an oxygen-containing gas in a vessel at a temperature elevated to a range of about 10.degree. to about 70.degree. C. below the melt point of the resin, upon reaching the desired level of pre-cure, the particulate resin is contacted with water thereby rapidly to reduce the temperature level below the temperature at which curing occurs.
