Abstract
The viscosity of a solution of graft copolymer resulting from solution graft copolymerization is greatly reduced, and the handling characteristics are improved, by adding water and a suspending agent to the solution to form a suspension. E.g., to a reaction solution resulting from grafting of styrene and acrylonitrile on EPDM in solution, there is added 20 parts water and 0.1 part polyvinyl alcohol, and the mixture is agitated to produce a low-viscosity suspension.
