  • Patent number: 10336852
    Abstract: 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. The amphiphilic character will result from the incorporation of hydrophilic poly(ethylene oxide) (PEO) side-chains. Various applications of the novel amphiphilic graft copolymer are also described including, but not limited to, thermoplastic elastomer, films, fibers, fabrics, gels, breathable packaging materials, additive for biodegradable system, surfactant, antistatic additives, polymer compatibilizers, phase transfer catalysts, solid polymer electrolytes, biocompatible polymers, or incorporation into the materials listed above.
