Abstract
A process, and the well-dispersed product thereof, for recovering solids from a latex of a grafted rubber concentrate having a rubber substrate and a glassy superstrate by: (a) adding a latex of said superstrate to said grafted rubber concentrate latex; (b) coagulating said latex with high shear to form a paste; (c) heating said paste to cause syneresis of said paste into polymeric particles; and (d) dewatering said particles.
