Abstraet--Carbazole units in copolymers can be cross-linked by reaction with a Lewis acid catalyst in methylene chloride. The reaction initially causes gel formation, followed by the development (with BF3. Et20) of a characteristic blue colour. The blue product has been shown to be a cationic dye of
Thermal degradation of poly (vinyl chloride ) (PVC ) was studied in nitrogen atmosphere in the presence of rubber seed oil and epoxidized rubber seed oil, barium and lead soaps of rubber seed oil, and epoxidized seed oil at various temperatures. The rate of dehydrochlorination at 1% degradation and
