摘要： The objective of the present invention is to provide a composition used as a thermal-latent polymerization initiator which does not catalyze a polymerization at ordinary temperature but can catalyze at lower temperature and which has an excellent catalytic ability. In addition, the objective of the present invention is to provide a thermal-latent polymerization initiator consisting of the composition, a method of polymerization using the thermal-latent polymerization initiator, and a curable composition containing the thermal-latent polymerization initiator. The composition according to the present invention is characterized in comprising tris (pentafluorophenyl) borane and an amine compound having a specific piperidine structure.

摘要： Metallic complexes having indenyl ligands can be used as an ingredient of a catalyst system. The catalyst system can be used in polymerizations of ethylenically unsaturated hydrocarbon monomers that include both olefins and polyenes. Embodiments of the catalyst system can provide interpolymers that include polyene mer and from 40 to 75 mole percent ethylene mer, with a plurality of the ethylene mer being randomly distributed. The catalyst system also can be used in solution polymerizations conducted in C5-C12 alkanes, yielding interpolymers that include at least 10 mole percent ethylene mer.
