Abstract: An organoborane complex is disclosed. The complex includes a blocking agent comprising a bifunctional Lewis base. The blocking agents include an amine group and a second functional group that has a lower Lewis basicity than the first functional group. The blocking is based on amino alkyl pyridines.

Abstract: A method to join pipe is disclosed using a curable one or two part adhesive composition comprising an effective amount of a boron containing initiator compound such as an organoborate, a stabilized organoborane complex, or combinations thereof; one or more monomers, oligomers, polymers or mixtures thereof having olefinic unsaturation which is capable of polymerization by free radical polymerization; and optionally a decomplexing agent. An especially preferred organoborane is one where a tertiary or quaternary nitrogen atom is bonded to the organoborane to prepare an amido-borate. In those embodiments where the nitrogen is quaternary, the quaternary nitrogen portion of the amido-borate is the cationic counter ion for the borate anion portion of the compound to which the quaternary nitrogen atom is bonded.

Abstract: A metal complex useful as a component of a catalyst composition for addition polymerizations comprising an anionic, polycyclic, fused ring ligand system containing at least 4 fused rings, at least one such ring comprising at least one heteroatom, said ligand being bonded to M by means of delocalized ?-electrons and an addition polymerization process using the same.

Abstract: The present invention relates to a method for preparing polymeric films, preferably electroactive films, with enhanced physical properties by the steps of applying to a substrate a solution of a polymer containing pendant labile solubilizing groups, then removing the solvent and a sufficient concentration of the labile solubilizing groups render the polymer less soluble in the solvent than before the labile groups were removed. It is believed that the removal of pendant soluble groups a) permits optimization of the semiconducting backbone for charge transport performance, b) allows direct control of microstructure in the final film, and c) renders the final film more robust during subsequent process steps needed to construct multilayer devices.
