A novel type of hollow polymer particles containing carboxyl groups was prepared from a widely available biophenylpropene trans-anethole (ANE). To prepare the hollow particles, we first prepared polymeric particles using vinyl acetate and maleic anhydride (MAH), and then such particles were taken as sacrificial templates for the subsequent formation of core/shell particles, which were synthesized by using ANE and MAH as comonomers and divinylbenzene (DVB) as cross-linking agent through precipitation polymerization. After removing the core in the prepared core/shell particles, we obtained hollow particles and then hydrolyzed the anhydride groups into carboxyl functional groups. The hollow particles were characterized by FT-IR, SEM, and TEM, and further used as absorbents. The maximum adsorption toward Cu²⁺ and methylene blue reached 270 and 940 mg/g, respectively. The recycling study showed that the biobased hollow particles can be easily restored and reused. The hollow particles may find practical applications as sustainable absorbents. The established methodology for preparing hollow polymer particles is expected to be applicable for other biophenylpropenes.

生物质反-基于茴香脑的中空聚合物颗粒：制备和可持续吸收剂的应用

从广泛可用的生物苯基丙烯反式茴香脑（ANE）制备了一种新型的含羧基的中空聚合物颗粒。为了制备中空颗粒，我们首先使用乙酸乙烯酯和马来酸酐（MAH）制备了聚合物颗粒，然后将这些颗粒用作牺牲模板，随后形成核/壳颗粒，并通过使用ANE和MAH作为共聚单体合成了核/壳颗粒通过沉淀聚合得到二乙烯基苯（DVB）作为交联剂。在除去制备的核/壳颗粒中的核后，我们获得中空颗粒，然后将酸酐基团水解成羧基官能团。空心颗粒通过FT-IR，SEM和TEM表征，并进一步用作吸收剂。对铜的最大吸附²⁺和亚甲基蓝分别达到270和940 mg / g。回收研究表明，生物基空心颗粒可以轻松恢复和再利用。中空颗粒可以作为可持续的吸收剂找到实际应用。预期的用于制备中空聚合物颗粒的建立的方法学将适用于其他生物苯基丙烯。
