Corn-based BPA alternative

I did promise to post some of my interviews from my recent bisphenol-A article on ICIS Chemical Business (ICB) so here's one about a possible alternative to BPA in epoxy resins.

Michael Jaffe, professor of biomedical engineering at the New Jersey Institute of Technology (NJIT), has developed a derivative of corn-based isosorbide that has the potential to replace BPA-based epoxy resins in a number of consumer products, including the lining of tin cans.

NJIT's patent "Thermoset epoxy polymers from renewable resources" (US Patent 7,619,056) awarded in November 2009 claimed that the derivative bisglycidyl ethers can be a potential substitute for BPA in the manufacture of thermoset epoxy ethers.
