Abstract

In the process of producing graft polymers by subjecting a polymer to ionizing radiation and to contact with a monomer polymerizable by free radicals, the monomer is, during the contacting of the polymer and monomer, additionally contacted with a polymerization inhibitor capable of substantially inhibiting homopolymerisation thereof while maintaining the polymer on which the graft is being formed substantially free from the action of the polymerization inhibitor. The inhibitor may e.g. be more soluble in the monomer phase than in the polymer or may more readily disperse by diffusion in the monomer phase than in the polymer phase, inhibitors specified being polyhydric phenols, benzoquinone, air and oxygen. In examples, plates of polyvinyl chloride are swollen in acrylonitrile and the swollen plates irradiated while partially immersed in liquid acrylonitrile in the presence of air. Other polymers and monomers which may be used are referred to in Specifications 801,528 and 809,838.ALSO:In the process for producing graft polymers by subjecting a polymer to ionizing radiation and to contact with a monomer polymerizable by free radicals, the monomer is, during the contacting of the polymer and monomer, additionally contacted with a polymerization inhibitor capable of substantially inhibiting homopolymerization thereof while maintaining the polymer on which the graft is being formed substantially free from the action of the polymerization inhibitor.
