1. A method of providing adhesion of an article to a fluorinated polymer surface which comprises intermittently subjecting at least a portion of the fluorinated polymer surface to from 0.1 to 30 seconds of plasma discharge in an atmosphere containing an organic amine to provide a modified fluoropolymer surface and bonding the modified fluoropolymer surface with the article by means of an adhesive disposed therebetween.

- 11. An article comprising a surface of fluoropolymer wherein at least a portion of the fluoropolymer surface has been modified by intermittently subjecting it to from 0.1 to 30 seconds of plasma discharge in an atmosphere containing an organic amine.
-
13. A method of providing adhesion of an article to a fluorinated polymer surface which comprises repeatedly moving at least a portion of the fluorinated polymer surface into and out of a plasma discharge zone in an atmosphere containing an organic amine to provide a modified fluoropolymer surface and bonding the modified fluoropolymer surface with the article by means of an adhesive disposed therebetween.
-
14. A composite comprising a first article having a surface of fluoropolymer which has been modified by repeatedly moving at least a portion of the surface into and out of a plasma discharge zone in an atmosphere containing an organic amine and which further comprises a second article which is bonded to the first article by an adhesive disposed between the second article and the modified fluoropolymer surface.
-
15. A method of providing adhesion of an article to a fluorinated polymer surface which comprises passing at least a portion of the fluorinated polymer surface through a series of spaced plasma discharge zones in an atmosphere containing an organic amine to provide a modified fluoropolymer surface and bonding the modified fluoropolymer surface with the article by means of an adhesive disposed therebetween.
