  • Patent number: 8501886
    Abstract: The invention is a two part polymerizable composition comprising in one part an organoboron compound capable of forming free radical generating species amine complex and in the second part one or more compounds capable of free radical polymerization and a cure accelerator 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, preferably two substituents on the aromatic ring selected from hydroxyl, ether and both, where there are two substituents they are located either ortho or para with respect to one another and a peroxide containing compound. The second part may further contain an agent capable of causing the organoboron compound to form free radical generating species upon contacting the two parts. The first part may further comprises one or more compounds capable of free radical polymerization. This facilitates formulating compositions that have commercially desirable volumetric ratios of the two parts.

  • Publication number: 20130174907
    Abstract: Disclosed are a sealing material for solar cell modules and a manufacturing method thereof capable of endowing good transparency and heat resistance to the sealing material for solar cell modules while using a polyethylene-based resin. The disclosed sealing material for solar cell modules uses a polyethylene-based resin with a density of 0.900 g/cm3 or less, and an MFR between 0.1 g/10 min and 1.0 g/10 min. The sealing material is obtained by melt molding a resin composition containing a polyethylene-based resin with density 0.890 g/cm3 or less, and a polymerization initiator contained at 0.02 mass % or more but less than 0.5 mass % of the composition, wherein the density difference of the resin composition before and after the melt molding is within 0.05 g/cm3, and the MFR difference of the resin composition before and after the melt molding is 1.0 g/10 min or greater.

  • Patent number: 8362165
    Abstract: The object of the present invention is to provide a process for producing a high-quality polymer microparticle having uniform particle size of the order of several micrometers to tens of micrometers by inverse suspension polymerization at high productivity while keeping excellent dispersion stability without causing aggregation among particles. The process is one for the production of polymer microparticles by inverse polymerization of a vinyl monomer and is characterized in that the inverse suspension polymerization is conducted dividing at least two steps, an oil-soluble oxidizing agent and a water-soluble reducing agent are used as a polymerization initiator, and the oil-soluble oxidizing agent is fed after the water-soluble reducing agent is fed.
