摘要

研究採微波輻射分散聚合法製備微米級（2～15 um）單分散共聚高分子微球，添加二甲基丙烯酸乙二酯（EGDMA）係為雙官能基壓克力單體，將使高分子微球內部形成交聯結構，有助提升微球玻璃轉移溫度（Tg）．研究探討微波輻射分散聚合法方式，實驗以微波功率、時間、單體比例、起始劑、分散劑進行研究，對於P（MMA/EDGMA）共聚高分分子微球其表面形態樣貌、單分散性探討。結果指出，微波聚合方式效率快，微球均一性佳，但高功率微波不利於高分子微球的成長。

In this study, microwave dispersion polymerization was used to prepare uniform micron (2~15μm) microspheres. Adding with the bi-functional acrylic monomers, ethyl glycol dimethacylate (EGDMA), would enable the formation of cross-linking structure inside microspheres to raise their glass transition temperature (Tg), To evaluate the microwave-assisted dispersion polymerization, the effects of microwave powers, time, monomer ratios, initiators and dispersants on the molecular surface morphology and the uniformity of Poly(MMA/EDGMA) copolymer microspheres were studied. The result indicates that the microwave polymerization is superior in both production efficiency and microsphere uniformity. But high power microwave is unfavorable for the growth of microspheres.
