13C n.m.r.用光谱分析了疏水性和亲水性聚甲基丙烯酸酯与淀粉的共聚物。用水解法释放接枝链后进行分析。正如自由基引发方法所预期的那样，它们都是间规的。解析了三联体、四联体、五联体或六联体信号。
13C n.m.r. spectroscopy has been used to analyse copolymers of hydrophobic and hydrophilic polymethacrylates on starch. The analysis was carried out after releasing the grafted chains by hydrolysis. They were all syndiotactic as expected from a radical initiation method. Triad, tetrad, pentad or hexad signals were resolved.
