Water termination of poly(arylene sulfide) curing

摘要

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 DEG to about 70 DEG 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.
