Abstract
The bondability of a polyolefin, particularly to cyanoacrylate adhesives, is improved by incorporating in the polyolefin a polymerization initiator capable of initiating the polymerization of the monomers constituting the cyanoacrylate adhesive. The polymerization initiator may, for example, be a sterically hindered nitrogen base and may be mixed with the polyolefin at a temperature above the polyolefin's glass transition temperature using, for example, co-extrusion or co-injection methods.
