Linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are stabilized against thermal degradation by the inclusion therein of certain phenolic compounds.

Stabilized olefin/carbon monoxide copolymers

A copolymer compositions comprising a major amount of an alternating copolymer of carbon monoxide with one or more olefinically unsaturated compounds and a minor of at least one stabilizing additive which is a zeolite-type trivalent-metal silicate containing a cation of an element of Group 2 of the Periodic Table is disclosed. This copolymer composition has and exhibits improved stability and contains a substantially reduced amount of residual solvent. Also disclosed is a process for producing this copolymer composition, and articles of manufacture made from this composition.

Stabilized copolymer compositions

Improved thermal stability and melt stability is demonstrated by stabilized compositions comprising a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon having incorporated therein a stabilizing quantity of a phenolic compound of defined structure.

Stabilized ethylene-carbon monoxide copolymer compositions

Process for the preparation of copolymers of carbon monoxide with one or more olefinically unsaturated compounds, by copolymerizing the monomers in the presence of a catalyst composition containing a Group-VIII metal and washing the formed copolymer by contacting the copolymer with a liquid which contains, dissolved in a solvent, a dicarboxylic or tricarboxylic acid having up to 8 carbon atoms, or a zinc, aluminum or magnesium salt thereof.

Process for the preparation of polyketone copolymers and copolymer wash

Polyketone polymer composition comprising a major amount of an alternating copolymer of carbon monoxide and an olefinically unsaturated compound and a minor amount of at least one additive, selected from: (a) the acid amides of monocarboxylic or polycarboxylic acids having from 5 to 30 carbon atoms and being optionally N-monosubstituted or N,N-disubstituted with C.sub.1 to C.sub.4 alkyl groups, and (b) aluminum compounds of formula Al(OX).sub.3, in which X stands for a hydrogen atom or a C.sub.1 to C.sub.4 alkyl group.

Polyketone copolymer composition comprising amide or aluminum compound

Linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are stabilized against thermal degradation by the inclusion therein of a stabilizing amount of a combination of a phenolic compound and an aromatic amine.

Stabilized ethylene monoxide copolymers

A process is disclosed for the preparation of a hydrocarbonaceous distillate and a hydrocarbonaceous residue, which comprises mixing a residual fraction of a product obtained by catalytic cracking or hydrocracking a hydrocarbonaceous feedstock, with a second hydrocarbonaceous fraction having such a boiling range that at least 50% w boils at a temperature above 400.degree. C., and subjecting the resulting mixture to a subatmospheric distillation yielding at least one distillate fraction and one residue. The residue thus prepared is a suitable component in bitumen compositions.
