ABSTRACT:
Solution blending of masterbatch of cationically functionalized polyvinyl acetate copolymer/silicate nanocomposite where the silicate is substantially exfoliated, and ethylene-vinyl acetate copolymer (EVA), produces product of increased tensile strength and Young's Modulus compared to neat EVA and reduced flammability compared to neat EVA. The product can be injection molded or compression molded or extruded without loss of these advantages.
