Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
A process for the surface treatment of a synthetic resin shaped article comprising contacting the surface of said article with a solution of at least one alkyl hypohalite in an organic solvent, said alkyl hypohalite being selected from the group consisting of butyl hypohalites and amyl hypohalites, the synthetic resin being a member selected from the group consisting of homopolymers of a monomer which is ethylene, propylene, styrene, vinyl chloride, methylmethacrylate or acrylonitrile, copolymers of at least two of said monomers, copolymers of at least one said monomer and a vinyl monomer, a mixture of one said resin and an ethylenically unsaturated polymer, polycarbonates, polyamide resins, polyether resins, polyester resins, phenol resins, urea-formalin resins, melamine-formalin resins, epoxy resins, acrylonitrile-butadiene-styrene resins, methacrylonitrile-butadiene-styrene resins, high impact polystyrenes and mixtures thereof.
Claim 2
Dependent Claim
128 words
A process for the surface treatment of a synthetic resin shaped article comprising contacting the surface of said article with a solution of at least one alkyl hypohalite in an organic solvent, said alkyl hypohalite being selected from the group consisting of butyl hypohalites and amyl hypohalites, the synthetic resin being a member selected from the group consisting of homopolymers of a monomer which is ethylene, propylene, styrene, vinyl chloride, methylmethacrylate or acrylonitrile, copolymers of at least two of said monomers, copolymers of at least one said monomer and a vinyl monomer, a mixture of one said resin and an ethylenically unsaturated polymer, polycarbonates, polyamide resins, polyether resins, polyester resins, phenol resins, urea-formalin resins, melamine-formalin resins, epoxy resins, acrylonitrile-butadiene-styrene resins, methacrylonitrile-butadiene-styrene resins, high impact polystyrenes and mixtures thereof.
Claim 3
Dependent Claim
22 words
A process according to claim 1, wherein the contact is carried out at 0° to 150°C for one second to 10 hours.
Claim 4
Dependent Claim
22 words
A process according to claim 2, wherein the alkyl hypohalite is used in solution in concentrations of at least 0.1% by weight.
Claim 5
Dependent Claim
13 words
A process according to claim 1, wherein the alkyl hypohalite is t.-butyl hypochlorite.
Claim 6
Dependent Claim
53 words
A process according to claim 1, wherein the alkyl hypohalite solution contains a solid material in a particulate form selected from the group consisting of magnesium, calcium, titanium, aluminum, iron, zinc and barium; the oxides, chlorides, carbonates and sulphates of said metals; and glass powder, asbestos, clay, pearlite, zeolite and inorganic silicon compounds.
Claim 7
Dependent Claim
17 words
A process according to claim 5, wherein the solid material has a particle size of 0.01-1000 microns.
Claim 8
Dependent Claim
25 words
A process according to claim 5, wherein the solid material is contained in amounts of up to 50% by weight of the alkyl hypohalite solution.
