摘要:
Linear alternating polymrs of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are provided increased melt stability by the inclusion therein of aluminum stearate.
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:
Improved melt stability without the loss of properties of strength and impact resistance are exhibited by blends of (a) linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and (b) ethylene-.alpha.,.beta.-ethylenically unsaturated acid copolymer.
摘要:
The melting point and the apparent degree of crystallinity of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are stabilized against undue lowering by intimately mixing with the polymer a succinic anhydride or hydrolysis product thereof.
摘要:
This invention is a process for the selective conversion of propylene and the n-butylenes to their dimers, in the presence of a heterogeneous palladium cyanide catalyst. The product dimers are predominantly of straight-chain structure.
摘要:
Linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are provided melt stability by the inclusion therein of barium acetylacetonate or titanium acetylacetonate.
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:
Thermoplastic polymer compositions of improved melt stability comprise a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, a partially zinc-neutralized acidic polymer containing moieties of an .alpha.-olefin and an .alpha., .beta.-ethylenically unsaturated carboxylic acid and metal salt wherein the metal is aluminum, magnesium or scandium.
摘要:
Stabilized polymer compositions comprise a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon incorporating a stabilizing quantity of a zinc aluminate and, optionally, an acidic polymer containing moieties of an .alpha.-olefin and an .alpha.,.beta.-ethylenically unsaturated carboxylic acid. The compositions demonstrate improved melt stability.
摘要:
Compositions comprising linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are provided improved melt stability upon incorporation of a stabilizing quantity of the reaction product of an oxy-bridged zinc-aluminum compound and an acidic polymer containing moieties of an .alpha.-olefin and an .alpha.,.beta.-ethylenically unsaturated carboxylic acid.
