聚丁二酸丁二醇-共-对苯二甲酸丁二醇酯的制备改性及应用研究进展OA

Polybutylene succinate-co-terephthalate(PBST)is a novel biodegradable green material that can replace traditional petroleum-based polymers,offering broad application prospects.However,PBST suffers from shortcomings such as low modulus,low yield strength,and poor heat resistance,limiting its use in high-performance applications.To address this,researchers conducted systematic investigations into both physical and chemical modifications of PBST.Results indicated that mechanical properties and thermal performance were significantly enhanced through methods such as physical blending,chain extension,and in-situ polymerization.These improvements open avenues for PBST applications in foaming,food packaging,and spinning.Future research will focus on further optimizing modification techniques and developing novel modified materials to achieve widespread adoption of PBST in more fields.
