Abstract

Disclosed is a copolymer film that includes a first comonomer including a chlorofluoro olefin and a second comonomer that is selected from the group consisting of itaconic acid, 2,3-dihydropyran, D-glucal, glycerine carbonate vinyl ether, 2-hydroxypropyl acrylate, maleic anhydride, vinylidene chloride, and mixtures thereof.

First claim

The invention claimed is:

1. A copolymer film comprising a copolymer that consists of a reaction product consisting of a first comonomer and a second comonomer, wherein:
the first comonomer is a chlorofluoro olefin;
the second comonomer is one of: D-glucal, glycerine carbonate vinyl ether, and 2-hydroxypropylacrylate; and
the first and second comonomers are randomly copolymerized in the copolymer.

2. The copolymer film of claim 1 , wherein the first comonomer is chlorotrifluoroethylene.

3. The copolymer film of claim 1 , wherein the copolymer film is disposed on an article, and wherein the article is a pharmaceutical packaging product.

4. A coated substrate packaging film comprising:
a substrate comprising polyvinyl chloride (PVC) or polyethylene terephthalate (PET) or polyethylene naphthalate (PEN) or polyimide; and
a copolymer in the form of a copolymer film coated on at least one surface of the substrate, the copolymer consisting of a reaction product consisting of a first comonomer and a second comonomer, wherein the first comonomer is a chlorofluoro olefin, wherein the second comonomer is one of: D-glucal, glycerine carbonate vinyl ether, and 2-hydroxypropylacrylate, and wherein the first and second comonomers are randomly copolymerized in the copolymer.

5. The coated substrate of claim 4 , wherein the first comonomer is chlorotrifluoroethylene.

6. The coated substrate of claim 4 , wherein the copolymer is applied on at least two surfaces of the substrate.

7. A copolymer film comprising:
a first comonomer that comprises chlorotrifluoroethylene (CTFE); and
a second comonomer that comprises either D-glucal or glycerine carbonate vinyl ether,
wherein the first and second comonomers are randomly copolymerized.

8. The copolymer film of claim 7 , wherein the copolymer film is disposed on an article, and wherein the article is a pharmaceutical packaging product.
