Abstract
Abstract Rubber articles, such as surgeon's gloves, are provided with a synthetic resin slip coating by contacting the rubber surface with a synthetic resin latex composition. The slip coating is adherent to the rubber substrate and is very extensible without adverse effect. The synthetic resin slip coating includes from 5 to 90 percent by weight of a first resin copolymer component selected from the group consisting of vinyl chloride-alkyl acrylate copolymer, vinylidene chloride-alkyl acrylate copolymer, and vinyl acetate-alkyl acrylate copolymer, and correspondingly, from 95 to 10 percent by weight of a second resin copolymer component selected from the group consisting of vinyl chloride-vinyl ester copolymer, and vinylidene chloride-vinyl ester copolymer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
A method of providing an adherent, extensible, essentially rubber free slip coating on a rubber surface comprising contacting a rubber surface with an aqueous synthetic resin latex essentially free of rubber and comprising from 5 to 90 percent by weight of a first resin copolymer component selected from the group consisting of vinyl chloride-alkyl acrylate copolymer, vinylidene chloride-alkyl acrylate copolymer, and vinyl acetate-alkyl acrylate copolymer and from 95 to 10 percent by weight of a second resin copolymer component selected from the group consisting of vinyl chloride-vinyl ester copolymer and vinylidene chloride vinyl ester copolymer, to provide a coating of said latex on said rubber surface, and permitting said coating to form a resin slip coating on said rubber surface.
Claim 2
Independent Claim
120 words
A method of providing an adherent, extensible, essentially rubber free slip coating on a rubber surface comprising contacting a rubber surface with an aqueous synthetic resin latex essentially free of rubber and comprising from 5 to 90 percent by weight of a first resin copolymer component selected from the group consisting of vinyl chloride-alkyl acrylate copolymer, vinylidene chloride-alkyl acrylate copolymer, and vinyl acetate-alkyl acrylate copolymer and from 95 to 10 percent by weight of a second resin copolymer component selected from the group consisting of vinyl chloride-vinyl ester copolymer and vinylidene chloride vinyl ester copolymer, to provide a coating of said latex on said rubber surface, and permitting said coating to form a resin slip coating on said rubber surface.
Claim 3
Dependent Claim
18 words
A method according to claim 1 wherein said rubber surface is a surface of a sheet-like rubber article.
Claim 4
Dependent Claim
15 words

Claim 5
Dependent Claim
17 words
A method according to claim 3 wherein said rubber glove is a sterile material rubber surgeon's glove.
Claim 6
Dependent Claim
24 words
