摘要

聚丁二酸丁二酯(PBS)及其共聚物是一类综合性能良好、加工性能优异的生物可降解高分子材料

是目前产业化并获得广泛应用的可全生物降解材料之一。本文总结了作者课题组在PBS材料合成、改性、结构和性能表征及其产业化方面的进展。通过高效催化剂的设计与制备，采用熔融缩聚直接制备高分子量的PBS。通过无规共聚、引入支化结构等分子结构设计方法，可以调节材料的结晶行为、物理机械性能和生物降解速率。基于构型（构象）匹配，设计了全组成范围的类质同晶体系聚（丁二酸丁二酯-

-富马酸丁二酯），进一步发现聚富马酸丁二酯是PBS的高效大分子型成核剂。通过共混和纳米材料复合改性，调控微观相结构和不同组分间的相互作用，大幅度提高材料力学性能。在此基础上，与企业合作，建成了年产万吨PBS及其共聚物树脂的生产线，生产的树脂可以挤出、注塑、吸塑和吹膜，已经用于超市购物袋和生物降解地膜等用途。

Abstract

Poly(butylene succinate) (PBS) and its copolymers

a type of completely biodegradable materials with good comprehensive properties and outstanding processability

have been industrialized and found wide applications. In this article

the progress of synthesis

modification

characterization of structure and properties as well as industrialization in our lab is summarized. We have synthesized PBS with high molecular weight via melt poly-condensation using specially designed catalyst. The crystallization behavior

physical and mechanical properties

and biodegradation rate are tuned via molecular design

such as random copolymerization and chain branching. Based on the concept of configuration (conformation) match

we designed poly (butylene succinate-

-butylene fumarate) showing isomorphism in the whole composition range. Poly (butylene fumarate) was found to be a highly efficient polymeric nucleating agent for PBS. In addition

blending and nanocomposites can considerably improve the mechanical properties of PBS via controlling the phase structure and polymer matrix/nano-filler interaction. Based on the fundamental research

we collaborated with companies to build facilities capable of producing PBS and its copolymers in a scale of 10000 tons annually. The resins have been used for extrusion

injection molding

thermoforming and film blowing. The products have found applications as supermarket bags and biodegradable mulch films

etc.
