Technical Abstract: In order for zein, a potentially significant co-product of the bio-ethanol industry, to be used in new markets, improved zein based products are needed. These products need to be produced by the most economical means possible. In the traditional plastics industry, extrusion techniques are the basis for most successful products. In addition, the zein used to make these products will need to be modified in such a way that they will be more resistant to water and other solvents. We will report on our efforts to modify zein using various cross-linking reagents in the melt state. The zein modification was undertaken in both batch processes as well as by reactive extrusion. Final articles were produced by compression molding and by injection molding. The articles produced had improved physical properties and improved resistance to a variety of solvents.
