Abstract

The present invention relates to a two-component composition comprising a first part (A) comprising a borane BH 3 -amine complex and an alkene compound, and a second part (B) comprising at least one radically polymerizable compound comprising at least one ethylenic bond, and to an adhesive composition obtained therefrom, and also to uses thereof. The invention also relates to articles made with this composition.

First claim

1 - 12 . (canceled)

13 . A two-component composition comprising:
a first part (A) comprising a borane BH 3 -amine complex and an alkene compound, said alkene compound being selected from the group consisting of:

R 11 representing a group comprising from 3 to 31 carbon atoms selected from the group consisting of a linear or branched alkyl group, an aryl group, an arylalkyl group, a cycloalkyl group, an —OR 12 group, an —SR 12 group and an —SiR 13 R 14 R 15 group;
R 12 being selected from the group consisting of a linear or branched alkyl group, an alkylaryl group, a cycloalkyl group, an acyl group;
R 13 , R 14 , R 15 being selected from the group consisting of, independently of one another, a linear or branched alkyl group, an aryl group, a cycloalkyl group or an alkoxy group;

2) an alkene compound of general formula [Chem 2]
H 2 C═CH—CH 2 —R 11

R 11 representing a group comprising from 3 to 31 carbon atoms selected from the group consisting of a linear or branched alkyl group, an aryl group, an alkylaryl group, a cycloalkyl group, an —OR 12 group, an —SR 12 group and an —SiR 13 R 14 R 15 group;
R 12 being selected from the group consisting of a linear or branched alkyl group, an arylalkyl group, a cycloalkyl group or an acyl group;
R 13 , R 14 , R 15 being selected from the group consisting of, independently of one another, a linear or branched alkyl group, an aryl group, a cycloalkyl group or an alkoxy group;

and/or
3) an alkene compound of general formula [Chem 3]

X being an oxygen atom, a sulfur atom or a bridge-forming —CH 2 — divalent radical;
n being an integer from 2 to 10; and
R 17 and R 18 representing, independently of one another, a hydrogen atom, a linear or branched alkyl group comprising from 1 to 10 carbon atoms, a linear or branched alkene group comprising from 1 to 10 carbon atoms or a —CH 2 — divalent radical forming a bridge with the ring; and

a second part (B) comprising at least one radically polymerizable compound comprising at least one ethylenic bond chosen from an acrylic monomer, a methacrylic monomer or a combination thereof.

14 . The two-component composition as claimed in claim 13 , wherein the amine is selected from the group consisting of diisopropylamine, N-methyldiisopropylamine, N-ethyldiisopropylamine, dicyclohexylamine, N-methyldicyclohexylamine, N-ethyldicyclohexylamine, di-sec-butylamine, di-tert-butylamine, 1,1,1,3,3,3-hexamethyldisilazane, N-methyl-1,1,1,3,3,3-hexamethyldisilazane, N-ethyl-1,1,1,3,3,3-hexamethyldisilazane, 2,6-dimethylpiperidine, N-methyl-2,6-dimethylpiperidine, N-ethyl-2,6-dimethylpiperidine, 7-azabicyclo[2.2.1]heptane, N-ethyl-7-azabicyclo[2.2.1]heptane, 1-azabicyclo[2.2.2]octane and combinations thereof.

15 . The two-component composition as claimed in claim 13 , wherein the radically polymerizable compound is selected from the group consisting of an acrylate, an acrylic acid, an acrylamide, an acrylonitrile, a methacrylate, a methacrylic acid, a methacrylamide, a methacrylonitrile and combinations thereof.

16 . The two-component composition as claimed in claim 13 , wherein the alkene compound is selected from the group consisting of decene, octene, allyltrimethylsilane, vinyltrimethoxysilane, vinyltriethoxysilane and combinations thereof.

17 . The two-component composition as claimed in claim 13 , wherein the borane BH 3 -amine complex and the alkene compound are present in part (A) of the composition in a molar ratio of 1:1 to 1:20.

18 . The composition as claimed in claim 13 , wherein the radically polymerizable compound has a weight content of 10% to 99% in part B of the composition.

19 . The composition as claimed in claim 13 , wherein the volume ratio of part (A) to part (B) is from 1:1 to 1:40.

20 . The two-component composition as claimed in claim 13 , wherein said composition is devoid of decomplexing agents for decomplexing the borane and the amine.

21 . An adhesive composition obtained by mixing parts (A) and (B) of the two-component composition as claimed in claim 13 .

22 . A method for binding two substrates together comprising applying the two-component composition of claim 13 .

23 . The method of claim 22 , wherein at least one of the two substrates has a surface energy of less than or equal to 45 mJ/m 2 .
