Abstract
A filled polymer compositions and methods of preparing filled polymer that include a plant biomass filler a plant biomass with a low aromatic carbon content, and (a thermoset polymer. The plant biomass filler may have a low lignin content or no lignin at all. The filler may also be heat treated to a temperature that provides a plant biomass filler with less than 49% aromatic content.
