Abstract
Blends of a major proportion of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and lesser proportions of a relatively high molecular weight poly(arylsulfone) polymer and a relatively low molecular weight poly(arylsulfone) oligomer demonstrate improved processability and improved tensile modulus and tensile strength.
Claims11
