Abstract
Abstract Surfaces of articles formed from (1) normally solid polymers of aliphatic mono-1-olefins and (2) elastomeric and resinous polymers of conjugated dienes and vinyl-substituted aromatic compounds are conditioned by contact with a fluorine-containing gas under conditions and for a period of time sufficient to render the surface receptive to adhesives, coatings, paints, inks, decorations, and the like. The fluorine-containing gas can be pure or admixed with up to about 99 volume percent inert gas.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
92 words
A process for treating a polymeric surface formed from (1) normally solid polymers of aliphatic mono-1-olefins and (2) elastomeric and resinous copolymers of conjugated dienes and vinyl-substituted aromatic compounds which comprises contacting said surface with a fluorine-containing gas under conditions and for a period of time sufficient to render said surface water-wettable and receptive to adherence of a second material selected from adhesives, coatings, paints, inks, decorations, and the like, and then contacting said surface with said second material under conditions which cause said second material to adhere to said fluorinated surface.
Claim 2
Dependent Claim
92 words
A process for treating a polymeric surface formed from (1) normally solid polymers of aliphatic mono-1-olefins and (2) elastomeric and resinous copolymers of conjugated dienes and vinyl-substituted aromatic compounds which comprises contacting said surface with a fluorine-containing gas under conditions and for a period of time sufficient to render said surface water-wettable and receptive to adherence of a second material selected from adhesives, coatings, paints, inks, decorations, and the like, and then contacting said surface with said second material under conditions which cause said second material to adhere to said fluorinated surface.
Claim 3
Dependent Claim
17 words
A process according to claim 1 wherein said polymer is polyethylene or a styrene/butadiene branch block copolymer.
Claim 4
Dependent Claim
24 words
A process according to claim 1 wherein said polymer is a molded or shaped article formed from polyethylene or a styrene/butadiene branch block copolymer.
Claim 5
Dependent Claim
27 words
A process according to claim 1 wherein said fluorine-containing gas is a mixture of inert gas and fluorine containing up to about 99 volume percent inert gas.
Claim 6
Dependent Claim
44 words
A process according to claim 1 wherein conditions include a temperature ranging from about 15° C. to about 100° C., a period of time ranging from about 30 seconds to about 30 minutes, and said fluorine-containing gas is a mixture of fluorine and nitrogen.
Claim 7
Dependent Claim
33 words
A process according to claim 5 wherein said polymer is polyethylene or a styrene/butadiene branch block copolymer and said gas is a mixture of about 90 percent nitrogen and about 10 percent fluorine.
Claim 8
Dependent Claim
22 words
A process according to claim 1 wherein said polymer is a styrene/butadiene branch block copolymer and said second material is an ink.
Claim 9
Dependent Claim
78 words
A process for coating a polymeric surface formed from normally solid polymers of aliphatic mono-1-olefins which comprises contacting said surface with a fluorine-containing gas under conditions and for a period of time sufficient to render said surface water-wettable and receptive to a polysulfide coating, coating said treated surface with a liquid organic polysulfide, and curing said polysulfide coating by heating at an elevated temperature sufficient to form a polysulfide coating that adheres tenaciously to the fluorine-treated polymeric surface.
Claim 10
Dependent Claim
78 words
A process for coating a polymeric surface formed from normally solid polymers of aliphatic mono-1-olefins which comprises contacting said surface with a fluorine-containing gas under conditions and for a period of time sufficient to render said surface water-wettable and receptive to a polysulfide coating, coating said treated surface with a liquid organic polysulfide, and curing said polysulfide coating by heating at an elevated temperature sufficient to form a polysulfide coating that adheres tenaciously to the fluorine-treated polymeric surface.
Claim 11
Dependent Claim
39 words
A process according to claim 8 wherein said polymer is a molded or shaped article formed from polyethylene and said fluorine-containing gas is a mixture of inert gas and fluorine containing up to about 99 volume percent inert gas.
Claim 12
Dependent Claim
44 words
A process according to claim 8 wherein conditions include a temperature ranging from about 15° C. to about 100° C., a period of time ranging from about 30 seconds to about 30 minutes, and said fluorine-containing gas is a mixture of fluorine and nitrogen.
