POLYMER COMPOSITIONS AND METHOD FOR PRODUCING THE SAME
A method of forming a compatible mixture of at least two normally incompatible polymers selected, respectively, from a first class comprising the polyolefins and a second class comprising the polymers obtained by the radical polymerization of monomers containing at least one vinyl group is described. The method consists of first preparing at least one graft copolymer from a polymer of the first class and a monomer which on polymerization gives a polymer of the second class. The graft copolymer is mixed at 125 to 200 deg C with from two to twenty times the weight of the graft copolymers of a mixtare of the polymers to be made compatible. A portion of the first class of polymers is preliminarily activated by irradiation. As an example, some of the first class polymers are polyethylene, polypropylene, polyisobutylene, and the like. Polystyrene, polyvinyl acetate, polyvinyl chloride, polyacrylonitrile, polyallyl chloride, polybutadiene, and the like make up the second class. (N.W.R.)
