| 20110160344 | RUBBER COMPOSITION FOR VULCANIZATION - The present invention provides a vulcanized rubber material having improved heat resistance while maintaining ozone resistance of an epihalohydrin rubber, and a rubber composition for vulcanization for producing the same. The invention further provides a vulcanized rubber material and a rubber composition for vulcanization, that can achieve the above objects without using an organonickel compound having a concern about toxicity, or if used, using the same as less as possible. The present invention relates to a rubber composition for vulcanization comprising (a) 100 parts by weight of an epihalohydrin rubber, (b) 0.01 to 0.5 part by weight of a copper salt of dithiocarbamic acid, (c) an acid acceptor, and (d) a polythiol type vulcanizing agent or a polyol type vulcanizing agent, a vulcanized rubber material obtained by vulcanizing the composition, and an automotive rubber part comprising the vulcanized rubber material. | 06-30-2011 |
| 20090202844 | INTERMEDIATE FILM OF LAMINATED SAFETY GLASS WITH ANTIGLARE FUNCTION AND NOVEL NEODYMIUM COMPOUND - [Problems] To impart an antiglare effect to a laminated glass making use of a polyvinyl butyral resin as an intermediate film without coloring the same. | 08-13-2009 |
| 20090023889 | PROCESS FOR PRODUCING ETHER POLYMER - An object of the invention is to provide a process for producing an ether (co)polymer in which molecular weight control is easy and post treatment of the reaction liquid after polymerization (solvent recovery, etc.) is easy; a chain transfer agent to be used in the production process; and an ether (co) polymer obtained according to the production process. The process for producing an ether (co) polymer of the invention is characterized in that an ether monomer is polymerized in a solvent, in the presence of a catalyst comprising a condensate of an organotin compound and an alkyl phosphate, and a chain transfer agent comprising, as the major ingredient thereof, an aliphatic polyalcohol of the following general formula (I), thereby producing an ether (co)polymer.
