Abstract
Abstract (Meth)acrylic acid esters of tricyclo [5.2.1.0. 2 .6 ]-decane derivatives having the formula ##STR1## wherein A represents the radical ##STR2## wherein R is a divalent hydrocarbon having 2 to 6 carbon atoms selected from the group consisting of alkylene, alkenylene, cyclohexylene, phenylene and tetrahydrophenylene, and R 1 is a member selected from the group consisting of hydrogen and methyl; as well as the process for the production of the esters, and their use in adhesive or sealing compositions which harden under exclusion of oxygen.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
89 words
(Meth)acrylic acid esters of tricyclo[5.2.1.0. 2 .6 ]-decane derivatives having the formula ##STR26## wherein A represents substituents in the positions selected from the group consisting of 3,8-, 3,9-, 4,8- and isomeric mixtures thereof, said substituents being the radical ##STR27## wherein R is a divalent hydrocarbon having 2 to 6 carbon atoms derived from a dicarboxylic acid which forms internal anhydrides selected from the group consisting of alkylene, alkenylene, cyclohexylene, phenylene, tetrahydrophenylene, and mixtures thereof, and R 1 is a member selected from the group consisting of hydrogen and methyl.
Claim 2
Dependent Claim
89 words
