In this paper, a novel kind of PMMA copolymer, P(MMA-co-MAA-co-SPMA), with permanently antistatic, high toughness, and high transparent properties, was synthesized via radical copolymerization. Herein, we selected the appropriate compatibilizer α-methacrylic acid (MAA) and release agent (lauryldiethanolamine) through the calculation of solubility parameters for industrial mass production. What is more, the polymer's molecular weight was increased by improving the polymer's synthesis process. The structure and properties of the obtained copolymer were characterized. With 0.6 wt% of the 3-sulfopropyl methacrylate potassium salt (SPMA), the copolymer exhibits nearly unchanged transparency with neat PMMA, and its unnotched impact strength reaches 16 kJ/m². The surface resistance of the copolymer could be reduced to 10¹⁰ Ω, which could be considered as antistatic materials. Finally, the antistatic mechanism was analyzed. The main reason is that the hydrophilic group absorbs water to form a conductive layer on the surface, and 3-sulfopropyl methacrylate potassium salt (SPMA) is an ionic monomer that can form ion channels in water molecules, further accelerating the leakage of accumulated electrostatic charges and improving the antistatic properties of the copolymer. The method of selecting compatibilizers and release agents through solubility parameters provides more opportunities for the development of PMMA with excellent comprehensive performance.

溶解度参数在制备永久抗静电、高韧性和优异光学性能的PMMA中的应用

在本文中，通过自由基共聚反应合成了一种具有永久抗静电、高韧性和高透明性能的新型 PMMA 共聚物 P(MMA- co- MAA- co- SPMA)。在此，我们通过对工业化批量生产的溶解度参数的计算，选择了合适的增容剂α-甲基丙烯酸（MAA）和脱模剂（月桂基二乙醇胺）。更重要的是，聚合物的分子量通过改进聚合物的合成过程而增加。表征了所得共聚物的结构和性能。使用 0.6 wt% 的 3-磺丙基甲基丙烯酸钾盐 (SPMA)，共聚物的透明度与纯 PMMA 几乎没有变化，其无缺口冲击强度达到 16 kJ/m ². 共聚物的表面电阻可以降低到10 ¹⁰  Ω，可以认为是抗静电材料。最后分析了抗静电机理。主要原因是亲水基团吸水在表面形成导电层，而甲基丙烯酸3-磺基丙酯钾盐（SPMA）是一种离子单体，可以在水分子中形成离子通道，进一步加速累积静电荷的泄漏提高共聚物的抗静电性能。通过溶解度参数选择增容剂和脱模剂的方法为开发综合性能优异的PMMA提供了更多机会。
