Incorporation of chemically reactive agents on resin particles

A process for incorporating chemically reactive agents on suitable synthetic resins comprising the steps of:

• introducing a batch of finely divided resin particles and chemically reactive agent into an enclosed mixing chamber having a plurality of blades attached to arms rotatable about a central axis within the chamber, the blades having enlarged surfaces relative to the arms to provide paddles for mixing of the resin particles and the reactive agent,
• rotating the blades in the mixing chamber at a blade tip speed of at least 18 meters per second to intensively mix and thermokinetically heat the batch of resin particles and chemically reactive agent,
• continuously monitoring the batch of resin particles and chemically reactive agent so as to maintain the temperature of the batch well below decomposition temperature of the reactive agent and below fluxing temperature of the resin particles,
• continuing the mixing cycle until the chemically reactive agent is locked to the resin particles,
• discharging the batch from the mixing chamber and
• cooling the discharged batch to avoid agglomeration of the resin particles to provide a product of unagglomerated particles of resin having reactive agent locked to the surface thereof.
