Abstract
Abstract Surfaces of articles formed from poly(arylene sulfide) resins are conditioned for the reception of adhesives, coatings, paints, and the like by contact with a fluorine-containing gas under conditions and for a period of time sufficient to render the surface water-wettable. The fluorine-containing gas can be pure or admixed with up to about 99 volume percent inert gas.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
47 words
A process for treating a poly(arylene sulfide) surface which consists essentially of contacting said surface with a fluorine-containing gas under a temperature and for a period of time sufficient to render said surface water-wettable and receptive to a second material including adhesives, coatings, paints and the like.
Claim 2
Dependent Claim
47 words
A process for treating a poly(arylene sulfide) surface which consists essentially of contacting said surface with a fluorine-containing gas under a temperature and for a period of time sufficient to render said surface water-wettable and receptive to a second material including adhesives, coatings, paints and the like.
Claim 3
Dependent Claim
13 words
A process according to claim 1 wherein said poly(arylene sulfide) is poly(arylene sulfide).
Claim 4
Dependent Claim
20 words
A process according to claim 1 wherein said poly(arylene sulfide) is a molded or shaped article formed from poly(phenylene sulfide).
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
42 words
A process according to claim 1 wherein said temperature ranges from about 65° C. to about 110° C., said period of time ranges from about 30 seconds to about 30 minutes, and said fluorine-containing gas is a mixture of fluorine and nitrogen.
Claim 7
Dependent Claim
28 words
A process according to claim 5 wherein said polymer is poly(phenylene sulfide) and said gas is a mixture of about 90 percent nitrogen and about 10 percent fluorine.
