摘要： This invention provides a method for preparing a polymethylmethacrylate spherical bead and in particular, it provides a method for preparing a polymethylmethacrylate spherical bead char¬ acterized in that it is prepared by preparing polymethylmethacrylate by polymerizing methyl- methacrylate monomers, evaporating remaining methylmethacrylate monomers by raising temperature up to at least 100 °C after the polymerization reaction, and washing the polymethyl¬ methacrylate with a mixed solvent of ethanol and water and vacuum drying them. The polymethylmethacrylate spherical beads in accordance with the invention not only can provide pure polymethylmethacrylate in its odorless condition by completely eliminating the remaining methylmethacrylate monomers that generate off-odor but also show no yellowing and at the same time, they are suitable for cosmetic materials or industrial materials because they are harmless to human and have no off-odor.
摘要翻译：本发明提供了一种制备聚甲基丙烯酸甲酯球形珠粒的方法，特别是提供了一种制备聚甲基丙烯酸甲酯球形珠粒的方法，其特征在于其通过聚合甲基丙烯酸甲酯单体制备聚甲基丙烯酸甲酯，通过升高温度蒸发剩余的甲基丙烯酸甲酯单体在聚合反应后至多100℃，用乙醇和水的混合溶剂洗涤聚甲基丙烯酸甲酯，并真空干燥。根据本发明的聚甲基丙烯酸甲酯球形珠不仅可以通过完全消除产生异味的剩余的甲基丙烯酸甲酯单体，而且在不臭的条件下可提供纯的聚甲基丙烯酸甲酯，同时也不显示黄变，同时它们适用于化妆品或工业材料，因为它们对人体无害，没有异味。
