摘要:
In one embodiment, the invention is a system for initiating free radical polymerization comprising: a) in one part, one or more amido-borate compounds containing one or more anionic amido-borate moieties comprising an organoborate wherein the boron atom is bonded to a nitrogen atom of ammonia or an organic compound containing one or more nitrogen atoms, such as a hydrocarbyl amine, a hydrocarbyl polyamine, or an aromatic heterocycle containing one or more nitrogen atoms, and a cationic counter ion and b) in a second part, a liberating compound which reacts with the nitrogen atom(s) bound to the boron atom upon contact with the amido-borate to form an organoborane radical. In another embodiment, the invention is a two part polymerizable composition comprising in one part, one or more amido-borate compounds and in the second part, a liberating compound which reacts with the nitrogen atoms bound to the boron atom upon contact with the amido-borate to form an organoborane radical and one or more compounds capable of free radical polymerization. The first part may further comprise one or more compounds capable of free radical polymerization. This facilitates formulating compositions that have commercially desirable volumetric ratios of the two parts.
