本文报道了一种以可再生生物质丁香酚为原料，通过简单有效的悬浮聚合方法制备的新型高分子微球。以丁香酚和甲基丙烯酰氯为原料，合成了单体甲基丙烯酸丁香酯（E-MA），并对其结构进行了鉴定。以偶氮异丁腈（AIBN）为引发剂，聚乙烯醇（PVA）为稳定剂，以E-MA为单体，同时作为交联剂，在水介质中通过悬浮聚合法制备了交联聚合物微球。所得微球以高产率获得，直径在500-800 μ π ι范围内，并且在相对高的速度下表现出显著大的吸油性。该微球可重复使用至少5次，最大吸收量变化不大。聚合物微球的制备方法为制备功能性更强的聚合物微球提供了一个通用的平台，有望在环境保护等领域获得重要的应用。
This article reports a novel type of polymeric microspheres derived from a renewable biomass, eugenol, via a facile and effective suspension polymerization approach. On the basis of eugenol and methacryloyl chloride, we first synthesized and then structurally identified the monomer eugenyl methacrylate (E-MA). By using E-MA as the sole monomer and simultaneously as the cross-linking agent, we successfully prepared cross-linked polymeric microspheres through suspension polymerization in aqueous media with 2,2-azoisobutyronitrile (AIBN) as the initiator and poly(vinyl alcohol) (PVA) as the stabilizer. The resulting microspheres were obtained in high yield with diameters ranging 500-800 pm and exhibited remarkably large oil absorbency in a relatively high speed. The microspheres can be reused for at least five times with little change in maximum absorption. The preparative strategy for the polymeric microspheres can be taken as a versatile platform for preparing more functional polymeric microspheres, which are expected to find significant applications in environmental protection and other fields.
