  • COMPOSITE PARTICLES, KIT, MATERIAL, AND METHOD FOR PRODUCING COMPOSITE PARTICLES
    Publication number: 20220169844
    Abstract: The present invention improves the long-term storage stability of an organoborane-Lewis base complex. First composite particles of the present invention include particles of an organic polymer (B), and an organoborane-Lewis base complex (A) contained in the particles. Second composite particles of the present invention include particles of an inorganic compound (B?), and an organoborane-Lewis base complex (A) adsorbed on the particles.

  • Polymerizable composition and kit, and polymerization initiator
    Patent number: 11130864
    Abstract: The present invention improves the long-term storage stability of a polymerizable composition including an organoborane and a polymerizable monomer. A polymerizable composition includes (A) an organoborane, (B) an acidic group-free polymerizable monomer, and (C) a stabilizer for the organoborane (A), the composition being such that when the composition, after being allowed to stand at 45° C. for 48 hours, is analyzed with an E-type viscometer at a temperature of 25° C. and a rotational speed of 50 rpm, the ratio of the viscosity after the standing to the viscosity before the standing (viscosity after standing/viscosity before standing) is less than 100.
