material and an organosilicon-containing additive (Brief, page 2).1 Independent claim
18 is illustrative of the invention:
18. A method of forming a coating on a substrate surface which coating
comprises SiOx groups by plasma treatment of the surface, wherein the substrate
comprises a blend of an organic polymeric material and an organosilicon-containing
additive which is substantially non-miscible with the organic polymeric material wherein
the organosilicon-containing additive is selected from the group consisting of
polydimethylsiloxane, α, ω-dihydroxpolydimethylsiloxane, α, ω-divinylpoly-
dimethylsiloxane, a polysilsesquioxane resin, an A-B-A copolymer, a B-A-B copolymer,
an A-B copolymer, an (A-B)n copolymer and an A-graft-B copolymer, wherein A is an
organic polymer, B is a siloxane, and n is a positive integer.
The examiner has relied upon the following references as evidence of
obviousness:
