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 |
20100216906 | MONOLITH SEPARATION MEDIUM FOR CHROMATOGRAPHIC USE AND METHOD OF PRODUCING THE SAME - A monolith separation medium comprising a skeletal phase and continuous pores forming a three-dimensional network structure, which has a functional group enabling the introduction of a new functional group on the surface of the skeletal phase. The skeletal phase has an average diameter of a submicron to micrometer size and is in a co-continuous structure of the non-particle-aggregation type. It is composed of an addition polymer of 1,3-bis(N,N′-diglycidylaminomethyl)cyclohexane as an epoxy compound with a bifunctional or higher amine compound, is rich in organic matters and is free from any aromatic-origin carbon atom. Thus, it is an organic polymer monolith separation medium of the non-particle-aggregation type. | 08-26-2010 |
20110130479 | ADHESION PROMOTER COMPOUNDS FOR OILED STEEL - Compounds of formula (I) in the field of heat-curing and two-component epoxy resin compositions, which may be used as adhesion promoters or adhesion promoter ingredients and methods of producing such compounds. Such compounds may be prepared as liquids. A heat-curing epoxy resin composition including at least one epoxy resin with more than one epoxy group per molecule on the average; at least one curing agent for epoxy resins, which is activated by elevated temperature; and at least one compound of formula (I). | 06-02-2011 |
20160040320 | METHOD OF MANUFACTURING POROUS THREE-DIMENSIONAL MICRO/NANOFIBROUS SCAFFOLD USING ELECTROHYDRODYNAMIC PROCESS AND POROUS THREE-DIMENSIONAL MICRO/NANOFIBROUS SCAFFOLD MANUFACTURED THEREBY - Provided are a method of manufacturing a porous three-dimensional microfiber, more particularly, a micro/nanofibrous scaffold using an electrohydrodynamic (EHD) process and a porous three-dimensional micro/nanofibrous scaffold manufactured thereby. | 02-11-2016 |
20160075872 | Toughening of Anhydride Cured Thermosetting Epoxy Polymers Using Grafted Triglycerides - Grafted triglycerides prepared from an epoxidized triglyceride and an acid anhydride containing 4 to 40 carbon atoms are reacted with an epoxy resin and an anhydride curing agent to yield an epoxy thermoset. By varying the length of fatty residues on the grafted triglyceride, the number of fatty residues per triglyceride, the identity of the epoxy resin and the anhydride curing agent, it is possible to prepare epoxy thermosets that exhibit superior physical properties compared to the properties of epoxy thermosets prepared without the grafted triglyceride, or as compared to epoxy thermosets wherein the epoxidized triglyceride is used in place of the grafted triglyceride. A significant improvement in fracture toughness with a minimal reduction of glass transition temperature may be thus achieved. | 03-17-2016 |
