摘要：
The paper reports on the possibility of direct use of some products of poly(ethylene terephthalate) glycolysis, bis(2-hydroxyethyl) terephthalate and ethylene glycol mainly, in the process of glass-fibre-reinforced plastics manufacturing. The addition of toluene diisocyanate as an intermediating agent was an important prerequisite for their incorporation into the resin composition. The composites containing products of poly(ethylene terephthalate) glycolysis up to 15% mass display improved mechanical properties in comparison with the unmodified samples.
