Organoborane polyoxyalkylenepolyamine complexes and adhesive compositions made therewith

An organoborane polyamine complex comprising organoborane and polyoxyalkylenepolyamine and having the structure ##STR14## wherein:

• R.sup.1 is an alkyl group having 1 to 10 carbon atoms;
• R.sup.2 and R.sup.3 are independently selected from alkyl groups having 1 to 10 carbon atoms and phenyl-containing groups;
• Am is polyoxyalkylenepolyamine and has a structure selected from the group consisting of
• H.sub.2 NR.sup.4 O--(R.sup.5 O).sub.w --(R.sup.6 O).sub.x --(R.sup.5 O).sub.y --R.sup.4 NH.sub.2 and
• [H.sub.2 NR.sup.4 O--(R.sup.5 O).sub.w ].sub.z --R.sup.7,
• wherein:
• R.sup.4, R.sup.5, and R.sup.6 are alkylene groups having 1 to 10 carbon atoms and which may be the same or which may be different;
• R.sup.7 is the residue of a polyol;
• the values of w, x, and y are selected such that the organoborane polyamine complex is a liquid at room temperature;
• z is 3 or 4;
• and
• the value of v is selected so as to provide an effective ratio of nitrogen atoms to boron atoms in the complex.
