Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
81 words
A method for modifying the surface of a polymer article, which comprises applying to the polymer article a macromer having a radical polymerizable double bond, followed by treatment with non-polymerizable plasma, wherein the macromer is an organic compound having a molecular weight of from 500 to 10 6 , whereby the organic compound reacts with radicals formed on the surface of the polymer article for graft reaction and is fixed to the surface of the polymer article by a covalent bond.
Claim 2
Independent Claim
81 words
A method for modifying the surface of a polymer article, which comprises applying to the polymer article a macromer having a radical polymerizable double bond, followed by treatment with non-polymerizable plasma, wherein the macromer is an organic compound having a molecular weight of from 500 to 10 6 , whereby the organic compound reacts with radicals formed on the surface of the polymer article for graft reaction and is fixed to the surface of the polymer article by a covalent bond.
Claim 3
Independent Claim
63 words
A method for modifying the surface of a polymer article, which comprises applying to the polymer article an organic compound having a radical polymerizable double bond, and contacting ozone gas thereto, whereby the organic compound reacts with radicals formed on the surface of the polymer article for graft reaction and is fixed to the surface of the polymer article by a covalent bond.
Claim 4
Independent Claim
63 words
A method for modifying the surface of a polymer article, which comprises applying to the polymer article an organic compound having a radical polymerizable double bond, and contacting ozone gas thereto, whereby the organic compound reacts with radicals formed on the surface of the polymer article for graft reaction and is fixed to the surface of the polymer article by a covalent bond.
Claim 5
Dependent Claim
31 words
The method for modifying the surface of a polymer article according to claim 1, wherein the macromer is a polymer having a molecular weight of from 1000 to 10 5 .
Claim 6
Dependent Claim
30 words
The method for modifying the surface of a polymer article according to claim 1, wherein the macromer is polyethylene glycol monoacrylate, polyethylene glycol diacrylate, polyethylene glycol dimethacrylate or polystyrene monoacrylate.
Claim 7
Dependent Claim
42 words
The method for modifying the surface of a polymer article according to claim 1, wherein the nonpolymerizable plasma is a plasma of a non-polymerizable gas selected from the group consisting of air, oxygen, nitrogen, neon, argon, Krypton, xenon, helium, hydrogen and ammonia.
Claim 8
Dependent Claim
44 words
The method for modifying the surface of a polymer article according to claim 2 wherein the organic compound is a monomer having at least one vinyl group, a diene monomer or a macromer having at least one radical polymerizable double bond in the molecule.
Claim 9
Dependent Claim
29 words
