Abstract

Multi-layered sheet structures comprising at least two layers, at least one of which consists of optionally doped polyacetylene, and at least one other layer joined thereto consists of a plastics material or inorganic material forming films or coatings, and processes for the production thereof.

Claims

1. A laminate comprising a doped polyacetylene film joined to a film-forming, plastic polyolefin layer.

2. A laminate according to claim 1 wherein the plastic layer is impermeable to oxygen.

7. A laminate in accordance with claim 1 wherein one plastic layer lies between two polyacetylene films.

3. A laminate comprising a polyacetylene film having two faces, where each face is joined to a plastic, film-forming polyolefin layer and where the edges of the laminate are sealed with the plastic.

4. A laminate according to claim 3 wherein the polyacetylene is doped polyacetylene.

5. A laminate according to claim 3 wherein the plastic layers and edges are impermeable to oxygen.

6. A laminate in accordance with claim 4 wherein the plastic layers and edges are impermeable to oxygen.

8. A laminate comprising a doped polyacetylene film joined to a film-forming, plastic layer where the plastic is selected from a halogenated polyethylene, a polyvinyl acetate, a polyvinyl alcohol, a polyacetal, a polystyrene, a polyester, a polycarbonate, a polysulfone, a polyurethane, or a polyamide.

9. A laminate according to claim 8 wherein the plastic layer is impermeable to oxygen.

14. A laminate in accordance with claim 8 wherein one plastic layer lies between two polyacetylene films.

10. A laminate comprising a polyacetylene film having two faces, where each face is joined to a film-forming, plastic layer and where the edges of the laminate are sealed with the plastic, where the plastic is selected from a halogenated polyethylene, a polyvinyl acetate, polyvinyl alcohol, a polyacetal, a polystyrene, a polyester, a polycarbonate, a polysulfone, a polyurethane, or a polyamide.

11. A laminate according to claim 10 wherein the polyacetylene is doped polyacetylene.

12. A laminate according to claim 10 wherein the plastic layers and edges are impermeable to oxygen.

13. A laminate in accordance with claim 11 wherein the plastic layers and edges are impermeable to oxygen.

15. A laminate comprising an oxygen impermeable, plastic polyolefin film having two-faces, where each face is joined to a polyacetylene film.

16. A laminate comprising a plastic film having two faces, where each face is joined to a polyacetylene film and where the plastic is selected from a halogenated polyethylene, a polyvinyl acetate, a polyvinyl alcohol, a polyacetal, a polystyrene, a polyester, a polycarbonate, a polysulfone, a polyurethane, or a polyamide.
