POLY 254 |
| An overview of our efforts to provide new monomers derived from waste cellulosic materials (Biomass) will be presented. Diols and dicacids of furan (and derivatives), dihydrofuran and tetrahydrofuran were used to form polyesters, polyamides and polyurethanes. Levulinic acid from hydrolytic degradation of waste cellulose could be converted to diphenolic acid (DPA), a Bis Phenol A analog containing a carboxyl group. DPA can be used to make homo- and co-polycarbonates. The carboxyl group in these materials has been used to append a variety of polymers of differing chemical character from the polycarbonate backbone. This approach has yielded a variety of functional polycarbonates, including ionomers and amphiphilic materials. |
