ABSTRACT:
The invention is a process to provide more granular, higher bulk density particulate poly(arylene sulfide ketone) or poly(arylene sulfide diketone) resins having associated therewith improved handling.
The process for treating a first slurry comprising a solid particulate poly(arylene sulfide ketone) or poly(arylene sulfide diketone) resin dispersed in a liquid medium comprising a polar organic compound, comprises: (a) liquifying the first solid particulate resin in the first slurry to form a first mixture comprising a liquified resin and the polar organic compound; (b) adding, to the first mixture, a sufficient amount of at least one separaton agent to produce a second mixture, and (c) reducing the temperature of the second mixture sufficiently to solidify the liquified resin to form a second slurry comprising a polar organic compound and a second solid particulate resin having a bulk density greater than the first solid particulate resin would if recovered.
In other embodiments, the above-described process is accomplished without generating pressure significantly greater than those generated during polymerization reactions of particulate poly(arylene sulfide ketone) or poly(arylene sulfide diketone) resins.
