Monodisperse bio-based polymer particles were successfully prepared through the dispersion polymerization of tulip-derived α-methylene-γ-butyrolactone (MBL) in ,-dimethylformamide/ethanol (7/3, w/w) at 65 °C with poly(vinylpyrrolidone) (PVP) as a colloidal stabilizer. The diameter of the polymer particles was well controlled by changing the composition of the reaction medium or PVP concentration. Furthermore, 100% bio-based poly(MBL) (PMBL) particles were prepared via the dispersion polymerization of MBL in water using hydrolyzed PMBL as a colloidal stabilizer, which was synthesized by hydrolysis of PMBL.
通过在 65°C 下，以聚维酮（PVP）为胶体稳定剂，在α-亚甲基-γ-丁内酯（MBL）在 -二甲基甲酰胺/乙醇（7/3，w/w）中的分散聚合，成功制备了单分散的生物基聚合物颗粒。通过改变反应介质的组成或 PVP 浓度，可以很好地控制聚合物颗粒的直径。此外，通过水解 PMBL 作为胶体稳定剂，在水中进行 MBL 的分散聚合，制备了 100%生物基聚（MBL）（PMBL）颗粒，PMBL 是通过 PMBL 的水解合成的。
