| 20080287595 | Amphiphilic Block Copolymer-Toughened Thermoset Resins - A composition comprising (1) a thermosettable resin selected from the group consisting of an epoxy resin, an epoxy vinyl ester resin, an unsaturated polyester resin or a mixture thereof, and (2) an amphiphilic mock copolymer dispersed in the thermosettable resin; fiber-reinforced plastics (FRP), coatings and composites prepared therefrom; and methods of preparing these. | 11-20-2008 |
| 20090123759 | Amphiphilic Block Copolymer-Toughened Epoxy Resins and Adhesives Made Therefrom - A curable adhesive epoxy resin composition including (a) an epoxy resin; (b) an amphiphilic block copolymer containing at least one epoxy resin miscible block segment and at least one epoxy resin immiscible block segment; wherein the immiscible block segment comprises at least one polyether structure provided that the polyether structure of said immiscible block segment contains at least one or more alkylene oxide monomer units having at least four carbon atoms; in an amount such that when the epoxy resin composition is cured, the bond strength of the resulting cured epoxy adhesive resin composition increases compared to an epoxy resin composition without said amphiphilic polyether block copolymer; and (c) at least one curing agent. The amphiphilic block copolymer is preferably an all polyether block copolymer such as a PEO-PBO diblock copolymer or a PEO-PBO-PEO triblock copolymer. | 05-14-2009 |
