Abstract
Provided herein are adhesive compositions comprising a polyurea-poly(meth)acrylate interpenetrating polymer network. Further provided are two-part curable adhesive compositions comprising a Part A initiator composition and a Part B activator composition. The Part A initiator composition comprises an organoborane-amine complex and the Part B activator composition comprises an isocyanate that is reactive with the amine portion of the organoborane-amine complex to liberate organoborane from the organoborane-amine complex. Further provided are methods of using an adhesive composition comprising a polyurea-poly(meth)acrylate interpenetrating polymer network, such as, for example, in joining and/or bonding together polyolefin materials (e.g., polypropylene random copolymer (PP-R) pipes).
