聚（丁二酸丁二醇酯-共-富马酸丁二醇酯）（PBSF）可以用作聚（丁二酸丁二醇酯）（PBS）的高效聚合物成核剂，并且这是基于外延结晶，即晶格匹配。利用PBSF能提高PBS球晶生长速率的独特特性，首次提出了一种结合PBSF添加量和自生核作用来调节PBS等温结晶球晶生长速率的新方法。
Poly(butylene succinate-co-butylene fumarate) (PBSF) can work as a highly efficient polymeric nucleating agent for poly(butylene succinate) (PBS) and this is based on epitaxial crystallization, namely matching of the crystal lattice. Benefiting from the unique behavior in which PBSF can enhance the spherulite growth rate (G) of PBS, a new method combining the addition of a fixed amount of PBSF and self-nucleation has been proposed to regulate G of isothermally crystallized PBS for the first time.
