  • Polymerizable compositions made with polymerization initiator systems based on organoborane amine complexes
    Patent number: 5690780
    Abstract: A polymerizable acrylic composition comprises:(a) at least one acrylic monomer;(b) an effective amount of an organoborane amine complex having the structure: ##STR1## 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 phenyl-containing groups and alkyl groups having 1 to 10 carbon atoms;R.sup.4 is selected from the group consisting of CH.sub.2 CH.sub.2 OH and (CH.sub.2).sub.x NH.sub.2 wherein x is an integer greater than 2;R.sup.5 is hydrogen or an alkyl group having 1 to 10 carbon atoms; andthe nitrogen atom to boron atom ratio is about 1:1 to 1.5:1; and(c) an effective amount of an acid for initiating polymerization of the acrylic monomer.The polymerizable acrylic compositions are especially useful for bonding low surface energy substrates.
    Type: Grant
    Filed: March 7, 1996
    Date of Patent: November 25, 1997
    Assignee: Minnesota Mining and Manufacturing Company
