Abstract

A laminate has at least two layers, at least one of which comprises a polymer having more than one perfluorocyclobutane group. Such polymers impart qualities of enviornmental or protection, chemical and solvent resistance, hydrolytic stability, lubricity, low dielectric, hydrostatic stability, weatherability, flame resistance, chemical resistance, hydrolytic stability, lubricity, environmental protection, scratch resistance, solvent resistance, surface passivation, water repellancy, lower surface refractive index, lower surface coefficient of friction, fluid barrier properties, oil repellancy, thermal stability, and/or reduced moisture pick-up. Additionally, the coatings are optically clear, easy to apply either neat, in a solvent or otherwise, have relatively low cure temperatures for their temperature resistance, and exhibit insulating and planarizing capabilities.

Claims

1. A laminate having at least two layers at least one of which comprises a matrix phase based on a polymer characterized by having more than one perfluorocyclobutane ring or an interpolymer of at least one compound having at least one perfluorocyclobutane ring and at least two functional groups reactive with di- or poly, functional compounds.

2. The laminate of claim 1 wherein the polymer has a backbone comprising perfluorocyclobutane groups, linking structures and hydrocarbon containing groups.

3. The laminate of claim 2 wherein the polymer is formed from at least one monomer having a structure represented by Formula 1 or II:

##STR2## wherein R represents an unsubstituted or inertly substituted group;

each X is independently a bond or any group which links R and a perfluorovinyl group;

m+1 is the number of --X--CF═

CF₂ units;

n and n'"'"' are the number of G and G'"'"' groups, respectively; and

G and G'"'"' independently represent any reactive functional groups or any groups convertible into reactive functional groups.

4. The laminate of claim 3 wherein the polymer has an average molecular weight of at least about 10,000.

5. The laminate of claim 3 comprising at least one layer of the polymer and at least one reinforcing or filling layer.

6. The laminate of claim 3 comprising at least one layer of the polymer and at least one other layer, hereinafter referred to as second layer, having a composition different from the layer of the polymer.

7. The laminate of claim 6 wherein the second layer comprises a material from the group consisting of wood, clay, stone, silicon, silicon oxide, germanium arsenide, barium ferrite, alloy of chromium and at least one other metal, metal, semiconductor, polymer of different composition, ceramic, glass, ceramitized glass, optical fiber, paper, synthetic fibers, cloth, fiber mat, or combinations thereof.

8. The laminate of claim 6 wherein the polymer forms a coating which is an environmentally protective, moisture resistant, hydrolytically stable, hydrostatically stable, radiation resistant or chemically resistant coating on the second layer.

9. The laminate of claim 6 wherein the laminate is in the structural form of carpet, tub, bathtub, shower, tile, swimming pool liner, siding, roofing, sleeping bag, sail, raincoat, protective clothing, mattress, furniture, drapery, pillow, toy, tent, camper, refrigerator, cookware, utensil for coated cookware, or combination thereof.

10. The laminate of claim 3 wherein the laminate is formed by segregation of the polymer from a material having a different composition from that of the polymer.

11. The laminate of claim 14 wherein the polymer having more than one perfluorocyclobutane group segregates from the material having a different composition such that it imparts thereto increased flame resistance, chemical resistance, hydrolytic stability, lubricity, environmental protection, scratch resistance, solvent resistance, surface passivation, water repellancy, lower surface refractive index, lower surface coefficient of friction, fluid barrier properties, oil repellancy, thermal stability, or reduced moisture pick-up over the same property the material would have in the absence of the polymer having more than one perfluorocyclobutane group.

12. The laminate of claim 3 wherein the polymer having more than one perfluorocyclobutane group imparts to the second layer of the laminate an increased flame resistance over the flame resistance the second layer would have in the absence of the polymer having more than one perfluorocyclobutane group.

13. The laminate of claim 3 wherein the polymer contains a material having a composition different from that of the polymer.

14. The laminate of claim 6 wherein the laminate is in the structural form of lined pipe, valve liner, a seal, a gasket, or combination thereof.

15. The laminate of claim 6 wherein the laminate is radiation or heat resistant and in the form of medical equipment, sick room equipment, medical or other clothing, bed linen, an instrument, ignition resistant paint, or combination thereof.

16. The laminate of claim 6 wherein the laminate has optical clarity and is in the form of eyeglasses, a window, coated glass, greenhouse, skylight, oven window, solar still, UV filter or combination thereof.

17. The laminate of claim 6 wherein the laminate is in the structural form of material with anti-fouling coating, object with underwater insulation, object with electrical insulation, object with mildew resistant coating, or combination thereof.

18. The laminate of claim 6 wherein the laminate is in the form of an automobile body part, vessel, mold, turbine blade, tub, food processing equipment, cryogenic container, autoclave, oven, heat exchanger, fuel container, or combination thereof.

19. The laminate of claim 6 wherein the polymer is a dielectric or insulator and the laminate is in the form of an electrical switch enclosure, battery, battery separator;

photographic, X-ray, or other imaging film;

or combination thereof.

20. The laminate of claim 6 wherein the laminate is microwavable including and in the form of cookware, popcorn bag, autoclave or container.

21. The laminate of claim 20 wherein the laminate is heat resistant and in the form of packaging, a roasting bag, popcorn bag, boiling bag, frozen food tray, retortable pouch, or combination thereof.
