ALKYD resin obtained from crude glycerol and waste polyethylene terephthalate
Nikola Todorov, Boryana Dzhundzhurova and Donka Todorova
Glycolysis of waste polyethylene terephthalate with crude glycerol was carried out at temperature of 210 °С. A mixture of 40 wt% sunflower oil and 40 wt% flax oil was added to the glycolysis product and a process of transesterification was performed. The mole ratio glycerol/vegetable oil was 1,5.
Medium oil alkyd resin was prepared by a process of polyesterification with phthalic anhydride. The course of the process was monitored by the change of the acid number. For comparison, a reference resin was synthesized with glycerol of 99% purity.
Films were prepared from resin solutions in xylene. Their physical properties and chemical stability were studied.
