PROCESS FOR THE PREPARATION OF GRAFT POLYMERS

Patent ·
OSTI ID:4747894

A process is provided for the manufacture of fiber or film-forming polymers of improved dyeability by graft polymerization of a minor quartity of one or more monomers to an acrylonitrile homopolymer or copolymer aquagel substrate. The aquagel substrate is impregnated with an N-vinyl heterocyclic monomer and then exposed to high energy ionizing radiation to initiate graft polymerization. The irradiated substrate is heated without irreversibly drying the aquagel to complete polymerization. (C.E.S.)
