Patent ID: 7638007

Claim:
A method for joining a substrate having a first surface to an object having a second surface comprising the steps of: (i) applying an effective amount of a curable adhesive composition to the first surface of the substrate, the second surface of the object or to both surfaces, wherein the adhesive comprises (a) an effective amount of a organoborane amine complex initiator and (b) one or more monomers, oligomers, polymers or mixtures thereof having olefinic unsaturation which is capable of polymerization by free radical polymerization and (ii) contacting the first surface of the substrate with the second surface of the object; wherein the organoborane amine complex initiator has the structure wherein B represents Boron; R 2 is separately in each occurrence C 1-10 alkly, C 3-10 cycloalkyl, two or more of R 2 may combine to form a cycloaliphatic ring; Q is a hydrolyzable moiety; R 11 is independently in each occurrence hydrogen, alkyl, alkoxy, alkenyl, alkyl amino or corresponds to the formula ((CR 14 H) r O) n —(NR 4 )—(CH 2 ) o —NH 2 with the proviso that at least (R 11 )′ is a primary amine leave this as is; R 12 is independently in each occurrence hydrogen, alkyl, aryl, alkoxy, and may further contain one or more primary, secondary or tertiary amines; R 14 is separately in each occurrence hydrogen or alkyl; R 4 is hydrogen, C 1-10 alkyl, C 6-10 aryl or C 7-10 alkaryl; a is a number of form 1 to 10; b is a number of from 0 to 1; m is separately in each occurrence a whole number of 1 or greater; p is separately in each occurrence a number of from 1 to 3; q is separately in each occurrence an integer from 1 to 2 wherein the sum of p and q on each silicon atom is 3; n is separately in each occurrence an integer of about 4 to about 400; o is separately in each occurrence an integer of about 1 to about 9; and r is separately in each occurrence an integer of 2 4.
