Abstract
Abstract Reduced odor is achieved in certain reactive fluid adhesive compositions while maintaining adequate adhesive properties by using higher molecular weight (C 10 -C 18 ) acrylic and methacrylic ester monomers in combination with minor quantities of diacrylate or dimethacrylate monomers, instead of lower molecular weight acrylic and methacrylic ester monomers generally used in such adhesives.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A composition suitable for use as an adhesive when combined with an aldehyde-amine condensation product, said composition comprising chlorosulfonated polyethylene, peroxy free radical generator, methacrylic acid, and a monomer mixture consisting essentially of a major proportion of at least one compound selected from the group consisting of C 10 -C 18 acrylates and C 10 -C 18 methacrylates, and a minor proportion of at least one compound selected from the group consisting of diacrylates and dimethacrylates, wherein the diacrylates and dimethacrylates comprise 10-30 weight percent of the monomer mixture.
Claim 2
Dependent Claim
89 words
A composition suitable for use as an adhesive when combined with an aldehyde-amine condensation product, said composition comprising chlorosulfonated polyethylene, peroxy free radical generator, methacrylic acid, and a monomer mixture consisting essentially of a major proportion of at least one compound selected from the group consisting of C 10 -C 18 acrylates and C 10 -C 18 methacrylates, and a minor proportion of at least one compound selected from the group consisting of diacrylates and dimethacrylates, wherein the diacrylates and dimethacrylates comprise 10-30 weight percent of the monomer mixture.
Claim 3
Dependent Claim
33 words
The composition of claim 1 wherein the C 10 -C 18 acrylates and C 10 -C 18 methacrylates are selected from the group consisting of iso-decyl methacrylate, n-decylmethacrylate, lauryl methacrylate and stearyl methacrylate.
Claim 4
Dependent Claim
36 words
The composition of claim 1 wherein the relative proportions of the chlorosulfonated polyethylene and the monomer mixture are from 25-2000 parts by weight of the monomer mixture per 100 parts by weight of the chlorosulfonated polyethylene.
Claim 5
Dependent Claim
36 words
The composition of claim 3 wherein the relative proportions of the chlorosulfonated polyethylene and the monomer mixture are from 50-500 parts by weight of the monomer mixture per 100 parts by weight of the chlorosulfonated polyethylene.
Claim 6
Dependent Claim
23 words
The composition of claim 1 wherein the at least one compound selected from the group consisting of diacrylates and dimethacrylates is ethylene dimethacrylate.
Claim 7
Dependent Claim
48 words
A method for adhering at least two surfaces to each other which comprises applying to at least one of said surfaces an aldehyde-amine condensation product, applying to at least one of said surfaces the composition of claim 1, and pressing said surfaces into intimate contact with each other.
Claim 8
Dependent Claim
138 words
A composition suitable for use as an adhesive when combined with an aldehyde-amine condensation product, said composition comprising chlorosulfonated polyethylene, peroxy free radical generator, methacrylic acid, and a monomer mixture consisting essentially of a major proportion of at least one compound selected from the group consisting of C 10 -C 18 acrylates and C 10 -C 18 methacrylates, and a minor proportion of at least one compound selected from the group consisting of diacrylates and dimethacrylates, wherein the diacrylates and dimethacrylates comprise 5-40 weight percent of the monomer mixture, provided that when the compound selected from the group consisting of C 10 -C 18 acrylates and C 10 -C 18 methacrylates is lauryl methacrylate, then the sum of the quantity of chlorosulfonated polyethylene and the quantity of diacrylates and dimethacrylates is 40-50 weight percent of the adhesive composition.
Claim 9
Dependent Claim
138 words
A composition suitable for use as an adhesive when combined with an aldehyde-amine condensation product, said composition comprising chlorosulfonated polyethylene, peroxy free radical generator, methacrylic acid, and a monomer mixture consisting essentially of a major proportion of at least one compound selected from the group consisting of C 10 -C 18 acrylates and C 10 -C 18 methacrylates, and a minor proportion of at least one compound selected from the group consisting of diacrylates and dimethacrylates, wherein the diacrylates and dimethacrylates comprise 5-40 weight percent of the monomer mixture, provided that when the compound selected from the group consisting of C 10 -C 18 acrylates and C 10 -C 18 methacrylates is lauryl methacrylate, then the sum of the quantity of chlorosulfonated polyethylene and the quantity of diacrylates and dimethacrylates is 40-50 weight percent of the adhesive composition.
