| 20090137751 | Process for preparing polyether alcohols with DMC catalysts using compounds bearing SiH groups as additives - Process for preparing polyether alcohols by polymerization by means of double metal cyanide catalysts (DMC catalysts), characterized in that, before or during the polymerization, one or more, optionally mixed additives consisting of compounds having one or more hydridic hydrogen atoms bonded to one silicon atom are added to the reaction mixture. | 05-28-2009 |
| 20100016520 | RADIATION-CURABLE COMPOSITION FOR OPTICAL RECORDING MEDIUM, AND OPTICAL RECORDING MEDIUM - In order to provide a radiation-curable composition which exhibits corrosion proof while maintaining mechanical properties and preservation stability and an optical recording medium using the composition, the radiation-curable composition for an optical recording medium comprises a urethane (meth)acrylate compound (A) and a compound (C) containing one or more epoxy groups, and has an acid content of 1.0×10 | 01-21-2010 |
| 20100120996 | METHOD FOR PRODUCING CRYSTALLINE POLYOXYALKYLENE POLYOL, AND RESIN OBTAINED BY USING THE SAME AS RAW MATERIAL - The present invention has its object to produce a highly reactive crystalline polyoxyalkylene polyol with a very high isotacticity at low cost, and provide polyurethane resins, and polyester resins which are excellent in sharp meltability. The present invention relates to a method for producing a crystalline polyoxyalkylene polyol having a number average molecular weight of 500 to 20,000 including performing ring-opening polymerization of an alkylene oxide (a) in the presence of a salen complex (B), the crystalline polyoxyalkylene polyol (A), and a polyurethane resin and a polyester resin produced by the crystalline polyoxyalkylene polyol (A). | 05-13-2010 |
| 20130012670 | SEALANT OF LIQUID CRYSTAL PANEL AND MODIFICATION METHOD THEREFOR - A sealant of a liquid crystal panel and a modification method therefor are disclosed. The sealant contains modified epoxy resins which is formed by a cross-linking and curing reaction between isocyanate-terminated tri-functional monomers and epoxy monomers. The modified epoxy resin has a plurality of trifurcate cross-linking long-chain structures, and each of the trifurcate cross-linking long-chain structures has three isocyanate groups, each of which is flexibly linked to one or more molecular groups of epoxy resin. The modified epoxy resin can enhance the adhesion property of the epoxy resin with surfaces of glass substrates and the stress-and-cracking resistance of the epoxy resin, while it can efficiently prevent from the miscible material problem between the epoxy resin and the liquid crystal material, so as to relatively lower the possibility of contaminating the liquid crystal material. | 01-10-2013 |
| 20130281640 | CYANATE ESTER COMPOUND, CURABLE RESIN COMPOSITION CONTAINING CYANATE ESTER COMPOUND, AND CURED PRODUCT THEREOF - There is provided a novel dicyanatophenyl-based difunctional cyanate ester which is in a liquid form at ordinary temperature and can obtain a cured product having an excellent low thermal expansion rate. There is disclosed a cyanate ester compound represented by the following formula (I): | 10-24-2013 |
| 20140046008 | POLYCARBONATE POLYOL COMPOSITIONS AND METHODS - In one aspect, the present disclosure encompasses polymerization systems for the copolymerization of CO | 02-13-2014 |
| 20140371406 | Curable Polyisocyanate Composition - Stable polyisocyanate composition comprising a compound comprising a group having the structure —CO—NH—O— in such an amount that the ratio of the number of —CO—NH—CO— groups to the number of isocyanate groups is at most equal to 1. Curable composition comprising this polyisocyanate composition, lithium halide, urea and an epoxy resin. | 12-18-2014 |
