Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
45 words
The process of adhering moist living tissue which comprises applying thereover an adhesive composition including 100 parts ethyl alpha-cyanOacrylate and 5 - 25 parts of poly (methyl-methacrylate) and maintaining said composition in film form on the moist tissue until the composition sets to cured condition.
Claim 2
Dependent Claim
95 words
The process of adhering moist tissue which comprises applying thereto the adhesive composition comprising a monomeric ethyl alpha-cyanoacrylate and a normally solid polymeric resinous anti-diffusion agent dissolved in the amount of 5 - 25 parts in 100 parts of said cyanoacrylate, said agent being selected from the group consisting of polymers and copolymers of C1-C8 alkyl and alkenyl esters of acrylic, methacrylic and alpha-cyanoacrylic acids and resinous polyesters of water soluble glycols and glycerine with polybasic organic acids, and maintaining said composition in film form on said tissue until the film sets to cured condition.
Claim 3
Dependent Claim
95 words
The process of adhering moist tissue which comprises applying thereto the adhesive composition comprising a monomeric propyl alpha-cyanoacrylate and a normally solid polymeric resinous anti-diffusion agent dissolved in the amount of 5 - 25 parts in 100 parts of said cyanoacrylate, said agent being selected from the group consisting of polymers and copolymers of C1-C8 alkyl and alkenyl esters of acrylic, methacrylic and alpha-cyanoacrylic acids and resinous polyesters of water soluble glycols and glycerine with polybasic organic acids, and maintaining said composition in film form on said tissue until the film sets to cured condition.
Claim 4
Dependent Claim
95 words
The process of adhering moist tissue which comprises applying thereto the adhesive composition comprising a monomeric butyl alpha-cyanoacrylate and a normally solid polymeric resinous anti-diffusion agent dissolved in the amount of 5 - 25 parts in 100 parts of said cyanoacrylate, said agent being selected from the group consisting of polymers and copolymers of C1-C8 alkyl and alkenyl esters of acrylic, methacrylic and alpha-cyanoacrylate acids and resinous polyesters of water soluble glycols and glycerine with polybasic organic acids, and maintaining said composition in film form on said tissue until the film sets to cured condition.
