Abstract

Abstract: A new type of graft copolymer EVA一g-PU was prepared;the grafting of polycthcr-polyurethane prepolymer onto EVA backbone was confirmed by FTIR and 13C-NMR characterization.Mechanical testing showed that the tensile strength and elongation at break of EVA一g-PU was far supcrior to neat EVA.Dynamic mechanical thermal analysis (DMA)showed that the storage modulus of EVA一g-PU increased with increasing PU prepolymer content. Thermal gravimetric analysis(TGA) testing showed that the introduction of PU prepolymer also increased the thermal stahilitics of EVA一g-PU copolymers.

Key words: ethylene-vinyl acetate copolymer, polyurethane prepolymer, graft copolymer
