甲基丙烯酸甲酯-丙烯酸甲酯共聚物的二维核磁共振光谱分析

Two dimensional NMR analysis of MMA-MA copolymer

通过二维(2D-NMR)核磁共振光谱技术,对甲基丙烯酸甲酯(MMA)和丙烯酸甲酯(MA)合成无规共聚物的谱峰归属进行分析,结合一维(1D-NMR)核磁共振光谱技术,可得到一种简便的结合单体含量计算方法,该方法可为聚甲基丙烯酸甲酯(PMMA)衍生产品的研发提供有价值的参考指标。

Through 2D-NMR spectroscopy,the peak assignment of random copolymers synthesized by methyl methacrylate(MMA)and methyl acrylate(MA)was analyzed.Combining with 1D-NMR spectroscopy,a simple calculation method for the content of monomers was obtained.This method can be used for the valuable reference index in research and development of derivatives of PMMA.
