Study on Irradiation Cross-Linking Modification and Biodegradability of Poly (Butylene Succinate)

The pure PBS material has been taken irradiation cross-linking modification in order to improve the melt strength of PBS. The mechanical properties, sanitation performance and biodegradable properties of the modified PBS were investigated. The results showed that the modified PBS has fine hygiene performance. The mechanical property increased, but it reduced rapidly after put into the specific soil. The weight loss rate of PBS reached 50.86% after degradation in humus for 56 days.
