Abstract
Reduced odor is achieved in certain reactive fluid adhesive compositions while maintaining adequate adhesive properties by using higher molecular weight (C.sub.10 -C.sub.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.

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.sub.10 -C.sub.18 acrylates and C.sub.10 -C.sub.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.
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.sub.10 -C.sub.18 acrylates and C.sub.10 -C.sub.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.sub.10 -C.sub.18 acrylates and C.sub.10 -C.sub.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.
