Abstract
The invention herein is directed toward a process of preparing free flowing thermoset resin particles of polybutadiene and includes the steps of physically mixing a filler material with polybutadiene followed by chopping the mixture into small particles or granules which are irregularly shaped. A vulcanizing agent can be added during the mixing step as well as other ingredients commonly added to polybutadiene resin formulations, as is customarily done in the art, without affecting the free flowing properties of the polybutadiene treated according to the process of this invention.
