ABSTRACT:
Polymer compositions comprising an intimate mixture of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and a poly(vinylidene fluoride) exhibit improved barrier properties. The poly(vinylidene fluoride) is also useful in a method of reducing the water vapor transmission rate of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon.
