A remarkable range of exciting new rubber, adhesive, elastomeric and plasticmaterials can be made by the cationic, thermal and free radical copolymerization of various soybean oils with styrene, acrylonitrile, dicyclopentadiene and divinylbenzene. These materials possess excellent thermal and mechanical properties, plus outstanding damping and shape memory properties.  Bioplastics from a range of other biological oils, including tung, corn, linseed and fish oils have also been prepared. In order to improve the polymer's performance, fillers, such as glass fiber, kenaf fiber, organic clay, wood flour, and agricultural co-products, such as soy hulls and distillers dried grains and solubles, have been used to reinforce these vegetable oil resins. The resulting biocomposites are very promising with significant improvement in the mechanical properties and thermal stability when compared with the resin alone. A number of novel new biobased waterborne polyurethane coatings and adhesives have also been prepared from agricultural oils.
