Abstract:

The paper reviewed the research progress in the preparation and applications of poly(butylene succinate)(PBS) and its blends. The current main synthesis technologies of PBS at home and abroad include direct esterification, transesterification, and chain extension. PBS is a type of completely biodegradable aliphatic polyester with good heat resistance and excellent mechanical properties, and it is capable of fundamentally solving the plastic white pollution as one of the most important biodegradable materials. The PBS blends with other brittle degradable polyesters can improve its toughness and biodegradability. Through blending with other renewable resources, The PBS blends can obtain an increase in rigidity, melting point, and mechanical properties, but a decrease in the cost. Through blending with a small quantity of inorganic fillers such as calcium carbonate and silica, PBS obtained not only a decrease in price but also an improvement in performance. In the present, PBS is mainly used in packaging materials, agricultural and forestry supplies, household goods, textiles, and medical products. The mechanical and gas barrier properties of PBS are two important indicators for its thin films. This review focused on the research progress in improving the mechanical properties and gas barrier properties of PBS composite films. Finally, the future research and development direction of PBS was prospected. The future direction in the PBS production technology will be to develop PBS products with high comprehensive performance, low cost, and green environment protection.
