Abstract
Unsaturated polyester resin waste is glycolytically degraded to obtain industrially useful glycolic raw material. It is possible to synthesize unsaturated polyester resin by reacting this glycolic raw material with unsaturated dibasic acid and saturated dibasic acid. It is also possible to synthesize polyurethane resin by reacting the glycolic raw material with a diisocyanate compound.
