Abstract

A three component blend of polymers comprising a polyethylene homopolymer or ethylene-alkene copolymer with an ethylene-vinyl acetate copolymer and either an ethylene-propylene copolymer or an ethylene-propylene-diene terpolymer. These three component blends are particularly suitable for rotational molding of shaped structures as they have synergistic properties of environmental stress crack resistance and high impact strength of the finished products. The disclosure also includes shaped structures comprising these blends.
