| 20100041814 | METHODS FOR PREPARING TOUGHENED EPOXY POLYMER COMPOSITE SYSTEMS - The present invention relates to epoxy resin compositions and more particularly to providing methods for toughening such epoxy resin systems. The methods include mixing a liquid epoxy resin with a glycidyl terminated modifying polymer and copolymerizing the epoxy resin and glycidyl terminated modifying polymer such that a liquid or gel phase comprising the modifying polymer separates from a solidified epoxy polymer to form the epoxy polymer composite system. | 02-18-2010 |
