  1. Block Copolymer Toughened Epoxy Timothy P. Lodge, University of Minnesota-Twin Cities, DMR 0212302 Principal Investigator Frank Bates (IRG-1) Description and Significance Fundamental research conducted by IRG-1 on the self-assembly of amphiphilic block copolymers in water has led to the recent commercialization of copolymer additives as a toughness enhancer in advanced epoxy formulations. The following text is extracted from a press release of November 21, 2007 (http://news.dow.com/dow_news/prodbus/2007/20071121a.htm): Dow Epoxy, a global business unit of The Dow Chemical Company and its affiliates (“Dow”), today introduced FORTEGRA™ Epoxy Tougheners, low viscosity materials for use in amine, DICY, anhydride and phenolic cured epoxy systems.... The FORTEGRA line is based on a specially designed self-assembling block copolymer that creates the particles needed for toughening the cured epoxy and, at the same time, does not result in big changes to other properties such as viscosity, cure speed or chemical resistance.
