Recent work on starch-based plastics in the author's laboratory is reviewed. We have blended starch with maleated polyolefins. Presence of a functional group improved the properties of the blends over those obtained with simple mixtures of starch and polyolefins. Up to 90% starch could be loaded, although products containing starch content of much more than 70% by weight were sensitive to moisture. These blends were injection molded using commercial plastic molds and have comparable cycle times. Weldline strengths are comparable to those of synthetic polymers. The properties of these materials were also found to be stable over a period of six months. The effect of processing on the physical and morphological properties of starch-based blends are discussed.
