20090253860 | Emulsifiers for Epoxy Resins - Disclosed is a process for the preparation of emulsifiers E1 which are obtained by (a) reacting a polyol with propylene oxide or a mixture of ethylene oxide and propylene oxide, to give an intermediate Z1, (b) reacting the intermediate Z1 with epichlorohydrin, forming an intermediate Z2, (c) reacting the intermediate Z2 with an adduct of ethylene oxide or a mixture of ethylene oxide and propylene oxide, with a C1-C22 monoalcohol, provided that on average at least one epoxide function of the intermediate Z2 is reacted and on average at least one epoxide function originating from the intermediate Z2 is retained. Compounds E1 are suitable as emulsifiers for preparing aqueous emulsions or dispersions of epoxy resins. | 10-08-2009 |
20100125109 | Use of Nanoporous Polymer Foams as Filter Materials - By reaction of one or more epoxy resins with an amphiphilic epoxy resin hardener in water in a phase inversion polymerization, nanoporous polymer foams are obtained. These foams are suitable as filter materials. | 05-20-2010 |
20100127204 | Use of Nanoporous Polymer Foams as Thermal Insulation Materials - By reaction of one or more epoxy resins with an amphiphilic epoxy resin hardener in water in a phase inversion polymerization, nanoporous polymer foams are obtained.

20110083805 | ADHESIVES - Compositions obtained by reacting the cardanol-containing raw material cashew nut shell liquid (CNSL) with (a) ammonia, or an amine which comprises at least one primary or at least two secondary amino groups, and (b) formaldehyde, are disclosed as adhesives. | 04-14-2011 |
20110284160 | 2-Component Adhesives - The invention relates to 2-component adhesives comprising one or more epoxy resins as a first component (E) and one or more amphiphilic epoxy resin hardeners as a second component (H), wherein the first component (E) and the second component (H) are reacted in water in a phase inversion polymerization. | 11-24-2011 |
20120010310 | Macropore-Containing Polymer Foams As Insulation Materials - Polymer foams comprising macropores, the macropores having average cross sections of above 500 nm, are obtainable by reacting one or more epoxy resins with one or more amphiphilic epoxy resin hardeners in water in a phase inversion polymerization, where, during the phase inversion polymerization, but after phase inversion has taken place, a volume increase of the internal voids which form initially, and which are present predominantly as micropores having average cross sections of below 500 nm, is induced such that the fraction of the macropores—relative to the entirety of micropores and macropores present in the polymer foam—at the end of the phase inversion polymerization is above 50% by volume. Polymer foams of the present invention are suitable for use as acoustic insulation materials in means of transport and in industrial and plant construction. | 01-12-2012 |
20130062551 | Use Of Nanoporous Polymer Foams As Heat-Insulating Materials - Nanoporous polymer foams can be obtained by reacting one or more epoxy resins with one or more amphiphilic epoxy resin hardeners in water in a phase inversion polymerization process, with the stipulation that the binder fraction of the polymer foams is within the range of 15 to 39.9 wt %. Said nanoporous polymer foams are suitable as heat-insulating materials. | 03-14-2013 |
20130062552 | Composite Material - The invention relates to composite materials, containing (i) a nanoporous polymer foam, which can be obtained by reacting one or more epoxy resins with one or more amphiphilic epoxy resin hardeners in water in a phase inversion polymerization process, and (ii) one or more inorganic fillers and/or inorganic fibers, with the stipulation that hollow glass balls are excluded as fillers. Said composite materials are suitable as heat-insulating materials. | 03-14-2013 |

20140128503 | DIGLYCIDYL ETHERS OF 2-PHENYL-1,3-PROPANEDIOL DERIVATIVES AND OLIGOMERS THEREOF AS CURABLE EPOXY RESINS - Cured epoxy resins are widespread on account of their outstanding mechanical and chemical properties. It is common to use epoxy resins based on bisphenol A diglycidyl ether or bisphenol F diglycidyl ether, but for many sectors these are problematic because of their endocrine effect. The present invention relates to 2-phenyl-1,3-propanediol diglycidyl ether derivates and to curable epoxy resin compositions based thereon, as alternatives to the bisphenol A or bisphenol F diglycidyl ethers and to the epoxy resin compositions based thereon. | 05-08-2014 |
