| 20090176952 | METHOD FOR PRODUCING MELT-MOLDABLE TETRAFLUOROETHYLENE COPOLYMER - To provide a method for producing a tetrafluoroethylene copolymer, wherein the polymerization rate is excellent, the copolymer to be obtained is excellent in mechanical properties such as the tensile strength, it is free from coloration and can be melt-molded. | 07-09-2009 |
| 20110275775 | CATALYST FOR LIVING RADICAL POLYMERIZATION - Provided is a catalyst used for a living radical polymerization method, which contains a central element consisting of carbon and at least one halogen atom binding to the central element. Further, a hydrocarbon compound can be used as a catalyst precursor. A monomer having a radical-reactive unsaturated bond is subjected to a radical polymerization reaction in the presence of the catalyst, consequently a polymer having narrow molecular weight distribution can be obtained, and thus the cost of the living radical polymerization can be remarkably reduced. The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst used, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor (no need of any post-treatments for a molded article), and the like. | 11-10-2011 |
| 20120245315 | PROCESS FOR THE POLYMERIZATION OF STYRENE - A process for the suspension polymerization of styrene monomer to produce polystyrene comprising the steps of (a) heating a polymerization suspension comprising the styrene monomer to a temperature of at least 60° C., (b) dosing an initiator to said heated polymerization suspension during the polymerization reaction over a period of more than 90 minutes to less than 5 hours, in a continuous manner or intermittently in at least 2 portions, said period starting at a monomer conversion of 65% of less and said initiator having a half-life at the temperature at which it is dosed of not more than 60 minutes, wherein a brominated flame retardant is present in the polymerization suspension during the polymerization reaction. | 09-27-2012 |
