摘要:
Non-miscible blends comprising, as a major component, a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and, as a minor component, a poly(alkylene oxide) polymer, exhibit improved processability.
摘要:
Plasticized compositions are produced by intimately mixing (a) a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and (b) an organic sulfone. Particularly preferred compositions comprise polymers of carbon monoxide and ethylene or polymers of carbon monoxide, ethylene and propylene, plasticized by the intimate presence therein of sulfolane.
摘要:
Compositions comprising linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and certain polar additives containing at least two groups of substantial carbon number show improved processing properties. A method of improving the processing properties of the linear alternating polymer comprises incorporating therein at least one of the polar additives.
