THE PHASE MORPHOLOGY OF RUBBER PLASTIC BLENDS

Thermoplastic vulcanizates contain particles of vulcanized rubber disp ersed in a thermoplastic resin, They are formed by the vulcanization o f the rubber during its mixing with the thermoplastic resin in the mol ten state. In the work presented here, we consider the evolution of th e blend morphology before dynamic vulcanization, The study considers t he rheological and interfacial effects on the phase morphology of the rubber-plastic blends during molten-state mixing, cold pressing, and c ompression molding. In addition, for blends of NR with polyethylene th e kinetics of the evolution of morphology during mixing with the polye thylene in the molten state was considered.
