Natural Oil-based Thermosets and Composites
A range of new materials can be obtained by the cationic, free radical, or thermal copolymerization of natural and modified oils with a number of petroleum-based comonomers. These novel biobased materials possess good thermal stabilities, good mechanical properties, and good damping and shape memory properties. Unique biobased polymers have also been prepared by the ring opening metathesis polymerization (ROMP) of modified oils and fatty alcohols in the presence of strained cyclic alkenes to form rubbery to hard materials. In order to improve the performance of these new materials, inorganic fillers and natural fibers have been used to reinforce the cationic, free radical, and ROMP resins. All of these materials exhibit properties similar to or better than related petroleum-based products.
