Plasticization of Polyvinyl Chloride with Reclaimed Polyvinyl Chloride-Polyurethane Mixture

The feasibility was studied of plasticization of rigid polyvinyl chloride with a reclaimed polyvinyl chloride-polyurethane mixture yielded by thermomechanochemical degradation of wastes of polyurethane foam coated with a polyvinyl chloride film. The molecular-weight distribution of the polyurethane component, temperatures of phase transitions, and physicomechanical properties of the polymer systems were studied as influenced by the preparation temperature of the reclaim.
