Zusammenfassung:	1325628 Grafted ethylene-vinyl acetate copolymers TOYO SODA MFG CO Ltd 23 June 1971 [26 June 1970 9 Sept 1970] 29489/71 Heading C3G A graft polymer is produced by polymerizing maleic anhydride and at least an equimolar amount of an alpha-olefin in the presence of an ethylene-vinyl acetate copolymer. In the examples, the polymerization is carried out in a benzene medium, the olefins used being propylene, ethylene and butene-1.
