Rheological Properties of Soy Protein Isolate and Polyurethane in Polyacrylonitrile/ Dimethyl sulfoxide Solution

摘要

Soy protein has attracted intensive research interests in recent year in the areas of plastic1, adhesive2, film3, elastomer4, fiber5,6 due to its renewability, biodegradability, and relatively low cost compared from animal resource. On the other hand, there are lots of amide groups, hydroxyl groups and amine group of soy protein isolate(SPI) molecule chain. Therefore, the intermolecular and intramolecular interaction can be occurred between these groups and other groups in another molecule chain.
