ABSTRACT:
A cast film, sheet or coating of a crosslinked graft copolymer of an organic polymeric substrate and an ethylenically unsaturated organic monomer is formed by effecting the graft copolymerization while the polymeric substrate and monomer are in solution in a solvent thereby to form the crosslinked graft copolymer in the form of a gel, subjecting the gel to high shear forces to convert it to a thixotropic suspension, forming the thixotropic suspension into a layer, and removing the solvent from the layer.
