Abstract
Abstract Polymerizable adhesives mixtures containing ethylenic double bonds capable of polymerizing and boron compounds as polymerization initiators, wherein the boron compounds are organoboron compounds and contain at least one boron-carbon bond or one boron-hydrogen bond and have practically no spontaneous combustibility in air. The adhesives harden after a short time to give stable adhesive bonds, even in the presence of moisture.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
103 words
A two-component reaction adhesive consisting essentially of a polymerizable system hardenable at room temperature and containing polymerizable ethylenic double bonds and an amont sufficient to initiate polymerization of an organoboron compound with sterically hindering groups and containing at least one boron-carbon bond or one boron-hydrogen bond and having practically no spontaneous combustibility in air and having the formula: ##STR4## wherein R' and R, separately or together, represent an aliphatic monocycle or dicycle with 3 to 25 carbon atoms and R o is selected from the group consisting of hydrogen and linear or branched or cyclic hydrocarbon having from 3 to 15 carbon atoms.
Claim 2
Dependent Claim
103 words
A two-component reaction adhesive consisting essentially of a polymerizable system hardenable at room temperature and containing polymerizable ethylenic double bonds and an amont sufficient to initiate polymerization of an organoboron compound with sterically hindering groups and containing at least one boron-carbon bond or one boron-hydrogen bond and having practically no spontaneous combustibility in air and having the formula: ##STR4## wherein R' and R, separately or together, represent an aliphatic monocycle or dicycle with 3 to 25 carbon atoms and R o is selected from the group consisting of hydrogen and linear or branched or cyclic hydrocarbon having from 3 to 15 carbon atoms.
Claim 3
Dependent Claim
29 words
The reaction adhesive of claim 1 wherein said amount sufficient to initiate polymerization is from 0.1% to 10% by weight, based on the total amount of the polymerizable portion.
Claim 4
Dependent Claim
17 words
The reaction adhesive of claim 1 wherein said organoboron compound is pre-adducted with an ethylenically unsaturated monomer.
Claim 5
Dependent Claim
17 words
The reaction adhesive of claim 2 wherein said organoboron compound is pre-adducted with an ethylenically unsaturated monomer.
Claim 6
Dependent Claim
12 words
The reaction adhesive of claim 1 wherein said organoboron compound is 9-borabicyclo-(3,3,1)-nonane.
Claim 7
Dependent Claim
12 words
The reaction adhesive of claim 3 wherein said organoboron compound is 9-borabicyclo-(3,3,1)-nonane.
