Abstract: Process for the manufacture of graft polymers from copolymers of ethylene with vinyl esters, acrylates or methacrylates by grafting an ethylenically unsaturated carboxylic acid thereto in the presence of a free-radical polymerization initiator. Homogeneous graft copolymers are obtained from which sheeting can be made. To this end, the unsaturated carboxylic acid is first caused to diffuse into the copolymer and the mixture is then extruded at temperatures above the crystallite melting point of the ethylene copolymer.

Abstract: Low MW chlorinated polyolefins, PVC and PVdC contg. 55-74 Wt. % chlorine are converted to expanded particles, of av. dia. 1-1000 mu. by spraying a soln. into a heated inert gas stream so that the thermoplastic foams. The particles are used as fillers for paints and putties based on aq. resin dispersions.
