ABSTRACT:
Soluble polymer resins are separated from a solution slurry with the use of a precipitation aid where the slurry contains the polymer resin in both a soluble form and a solid particulate phase. The precipitation aid absorbs onto the surface of the solid polymer resin particulates and is a suitable blend component for formulations of the polymer resin. The solution slurry may be concentrated and heated prior to precipitation of the polymer resin.
