Patent number: 10336852Abstract: A novel amphiphilic graft copolymer is described. A process to make amphiphilic graft copolymers via grafting either poly(ethylene oxide) or polylactide side chains onto an EVA platform using oxo-anion ring-opening polymerization chemistry is also described. Polyethylene or polypropylene based graft copolymers are prepared starting from poly(ethylene-co-vinyl acetate) or maleic anhydride grafted isotactic polypropylene respectively.
