Abstract
A process for the production of a graft copolymer comprises reacting an irradiated polymer in a reaction mixture comprising a first phase and a second phase. The first phase comprises a source of at least one non-water soluble monomer and the second phase comprises water and optionally, a water miscible organic solvent. The first and second phases are substantially immiscible and non-emusifiel. A high degree on monomer conversion is achieved.
