Abstract
Official abstract text for this publication.
Fluorinated macromonomers, a PCTFE-g-poly(M) graft copolymer, and moisture barrier films and articles formed therefrom are provided. The PCTFE-g-poly(M) graft copolymers have a PCTFE backbone component and a plurality of pendant groups attached to the PCTFE backbone component.
First claim
Opening claim text (preview).
What is claimed is: 1. A poly-chlorotrifluoroethylene (PCTFE) graft copolymer having a PCTFE backbone component and a plurality of polymeric pendant groups poly(M) attached to said PCTFE backbone component (PCTFE-g-poly(M)), wherein M is a monomeric unit of the polymeric pendant groups, and wherein the monomeric unit M comprises chlorotrifluoroethylene and the polymeric pendant groups poly(M) comprise PCTFE. 2. The PCTFE-g-poly(M) graft copolymer of claim 1 comprising from about 2 to about 20 pendant groups attached to the PCTFE backbone component. 3. A film formed from the PCTFE-g-poly(M) graft copolymer of claim 1 . 4. An article comprising the film of claim 3 . 5. The PCTFE-g-poly(M) graft copolymer of claim 1 wherein the PCTFE backbone component comprises one or more four-carbon chain units. 6. The PCTFE-g-poly(M) graft copolymer of claim 1 wherein the PCTFE backbone component comprises at least two four-carbon chain units. 7. The PCTFE-g-poly(M) graft copolymer of claim 1 wherein the PCTFE backbone component comprises at least three four-carbon chain units. 8. A poly-chlorotrifluoroethylene (PCTFE) graft copolymer having a PCTFE backbone component and a plurality of polymeric pendant groups poly(M) attached to said PCTFE backbone component (PCTFE-g-poly(M)), wherein M is a monomeric unit of the polymeric pendant groups, and wherein the monomeric unit M comprises vinylidenefluoride (VDF) and the polymeric pendant groups poly(M) comprise poly-vinylidenefluoride (PVDF). 9. The PCTFE-g-poly(M) graft copolymer of claim 8 comprising from about 2 to about 20 pendant groups attached to the PCTFE backbone component. 10. A film formed from the PCTFE-g-poly(M) graft copolymer of claim 8 . 11. An article comprising the film of claim 10 . 12. The PCTFE-g-poly(M) graft copolymer of claim 8 wherein the PCTFE backbone component comprises one or more four-carbon chain units. 13. The PCTFE-g-poly(M) graft copolymer of claim 8 wherein the PCTFE backbone component comprises at least two four-carbon chain units. 14. The PCTFE-g-poly(M) graft copolymer of claim 8 wherein the PCTFE backbone component comprises at least three four-carbon chain units. 15. A poly-chlorotrifluoroethylene (PCTFE) graft copolymer having a PCTFE backbone component and a plurality of polymeric pendant groups poly(M) attached to said PCTFE backbone component (PCTFE-g-poly(M)), wherein M is a monomeric unit of the polymeric pendant groups, and wherein the monomeric unit M comprises 4-bromo-3-chloro-3,4,4-trifluoro-1-butene (BCTFB) and the polymeric pendant groups poly(M) comprise poly-(4-bromo-3-chloro-3,4,4-trifluoro-1-butene) (poly-BCTFB). 16. The PCTFE-g-poly(M) graft copolymer of claim 15 comprising from about 2 to about 20 pendant groups attached to the PCTFE backbone component. 17. A film formed from the PCTFE-g-poly(M) graft copolymer of claim 15 . 18. An article comprising the film of claim 17 . 19. The PCTFE-g-poly(M) graft copolymer of claim 15 wherein the PCTFE backbone component comprises one or more four-carbon chain units. 20. The PCTFE-g-poly(M) graft copolymer of claim 15 wherein the PCTFE backbone component comprises at least two four-carbon chain units.
