Embodiment Construction

[0012] Polymerization initiators are organoboron-containing compounds capable of forming trivalent organoboron compounds. In a preferred embodiment, the free radical generating species is a trivalent organoboron compound. Preferred boron-containing compounds are tetravalent in that they have four bonds to boron, at least three of which are covalent, one of which may be covalent or in electronic association with the complexing agent. When a boron-containing compound is contacted with another species, referred to herein as a releasing compound, free radical-generating species are formed, such as trivalent boron compounds. The free radical generating species generates free radicals by reacting with ambient oxygen. In embodiments where the boron-containing compound is tetravalent, such contacting results in the removal of one of the ligands bonded or complexed to the boron atom, converting it to trivalent borane. A free radical generating species is a compound that contains or g...

Abstract

The invention is a two part polymerizable composition comprising in one part i) an organoboron compound capable of forming free radical generating species; and in the second part ii) one or more compounds capable of free radical polymerization; iii) one or more cure accelerators comprising a) at least one compound containing a quinone structure or b) at least one compound containing at least one aromatic ring and one or more substituents on the aromatic ring selected from hydroxyl, ether and both and a compound with a peroxide moiety; and iv) one or more vinyl functional modifiers having a glass transition temperature of -50° C. or less.

Description

[0001] Equity claims on filing date [0002] This application claims the benefit of the filing date of US Application Serial No. 11 / 546,753, filed October 12, 2006, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to accelerated polymerizable compositions comprising compounds containing moieties capable of undergoing free radical polymerization, organoboron compounds capable of forming free radical generating species, and adhesives based on such compositions. Species can initiate free radical polymerization. In another embodiment, the present invention is directed to a method of polymerizing a compound containing a moiety capable of free radical polymerization, and to a method of adhering a substrate using the composition. Background technique [0004] Low surface energy olefins such as polyethylene, polypropylene, and polytetrafluoroethylene have many attractive properties in a variety of applications such a...
