ABSTRACT:
Compositions comprising soluble and/or thermoplastic polyurethanes mixed with copolymers of ethylene and unsaturated esters of fatty acids show improved resistance to abrasion. Films made from the compositions show a reduced tendency to exhibit blocking. Use of ethylene copolymers mixed with additives also provides a useful way of mixing additives into polyurethanes.
