Abstract: Chemically reactive agents may be locked to particles of suitable synthetic resins without wholly fluxing the resins. Thus a high quality intermediate product is obtained having no premature reaction taking place, suitable for further techniques. The process comprises the steps of intensively mixing and thermokinetically heating a batch of finely divided resin particles, with a chemically reactive agent, in an enclosed mixing chamber with a plurality of blades attached to arms rotating about a central axis within the chamber, and having a blade tip speed of at least about 18 meters per second, mixing the batch until the chemically reactive agent is locked to the resin particles, ensuring that temperature of the batch stays well below decomposition temperature of the reactive agent and below fluxing temperature of the resin particles, discharging the batch from the mixing chamber and cooling the discharged batch to avoid agglomeration of the resin particles.
