Claims22
A melt processed polymer material having improved oxygen, water and/or carbon dioxide barrier properties comprising:
- a polymer comprising at least one linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon which has been heat treated to a temperature in the range of 2.degree.-40.degree. C. above the melting point of the linear alternating polymer then cooled at a rate of about 1.degree. C. to 20.degree. C. per minute.
A laminar structure prepared from a substrate and a melt processed polymer material wherein said material comprises a polymer comprising at least one linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, and said polymer has been heat treated to a temperature in the range of about 2.degree.-40.degree. C. above the melting point of said polymer then cooled at a rate of about 1.degree. C. to 20.degree. C. per minute.
An article of manufacture prepared from a melt processed polymer material having improved oxygen, water and/or carbon dioxide barrier properties, and wherein said material comprises at least one linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon which has been heat treated to a temperature in the range of 2.degree.-40.degree. C. above the melting point of the linear alternating polymer then cooled at a rate of about 1.degree. C. to 20.degree. C. per minute.
