A stabilized polymer composition comprising a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, and a melt stabilizing agent comprising of at least one compound having at least one or more hydroxyl group. A process for preparing the composition and articles of manufacture produced from the composition are also disclosed.

Stabilized polyketone blend

Polymer compositions comprising linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon filled with mica are prepared without the use of a coupling agent.

Polyketone compositions

A polymer material having barrier properties prepared from a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, a process for preparing this polymer material, a laminar structure and an article prepared from the polymer material.

Melt processed polyketone-based barrier polymer materials

This invention discloses a method of fabrication of a shelf stable, dimensionally heat stable, impact resistant, retortable, hot fillable container apparatus which is suitable for oven use. The container apparatus has a shaped first material layer formed from a linear alternating polymer of carbon monoxide, ethylene and propylene, and a cooperatively shaped second material layer formed by coating a copolymer of vinylidene chloride material on at least one untreated side of the first material layer, preferably by impact spraying. The thicknesses of the material layers are selected such that the water percent weight loss per year of any contents stored in the container is less than 3% per year.

Method for the fabrication of a multi-ovenable, retortable container

A process for preparing a melt processed polymer material having improved oxygen, water or carbon dioxide barrier properties wherein a quantity of a linear alternating polymer of carbon monoxide and at least one ethlenically unsaturated hydrocarbon is melt processed to form a film, heated to a temperature ranging from about 2.degree. C. to about 40.degree. C. above the melting point of the polymer, and cooling the heated melt processed film at a moderate rate between about 6.degree. C. and about 10.degree. C. per minute.

Process for preparing melt processed polyketone-based barrier polymer

A process for treating a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon with a fluorine to thereby affect the water vapor transmission rate through the polymer, as well as articles and laminar structures produced by that process.
