Development of compositions from waste of polypropylene and polyethylene terephthalate and research of their technological and thermal properties

The article presents the results of determining melting point and melt flow rate, Vicat heat resistance a composition made polypropylene waste from study polyethylene terephthalate. It has been established that with an increase in content terephthalate, according to increase, rate compositions decreases. Hildebrand solubility parameters packing density macromolecules are calculated using increment method. thermal characteristics were investigated by derivatography Their decomposition onset temperature, amount energy consumed for polymers polymer determined. was revealed terephthalate secondary more thermostable than primary polypropylene.
