Study on Quaternary Ammonium Polymers Containing of 8-Hydroxyquinolin

通过8-羟基喹啉(8Q)的氯甲基化,首先合成了5-氯甲基-8-羟基喹啉盐酸盐(C8Q),然后合成了甲基丙烯酸二甲胺基乙酯(DM)含量分别为9.69%、16.29%和36.55%的丙烯酸甲酯共聚物(CPA1、CPA2、CPA3和CPA4),最后使C8Q挂接到CPA1、CPA2和CPA3上得到含8Q的季铵型高分子化合物CPA1-8Q、CPA2-8Q和CPA3-8Q。通过凝胶渗透色谱法(GPC)确定了CPA1、CPA2、CPA1-8Q和CPA2-8Q为高分子量聚合物,通过溶解实验、FT-IR和UV-vis证明了挂接反应是成功的,得到了目标产物。

In order to prepare polymers with 8-hydroxyquinoline end groups, functional 8-hy- droxyquinoline （5-chloromethyl-8-quinolinol hydrochloride） was firstly obtained by chloromethylation of 8-hydroxyquinoline. Then CPA1, CPA2and CPA3（the co-polymerization of methacrylic esters） was synthesized by containing of the methacrylic dimethylamidocyanogen ethanolesters （9. 69%, 16.29% and 36. 55%）. Followly, the opposite hight molecular weight quaternary ammonium polymer containing of 8-hydroxyquinolin（CPA1-8Q, CPA2-8Q and CPA3-8Q） was synthesized by using C8Q ingraft to CPA1, CPA2and CPA3. CPA1, CPA2, CPA1-8Q and CPA2-8Q are opposite hight molecular weight polymer vis to mensurate the molecular weight and distributing of the CPA1, CPA2, CPA3, CPA1-8Q, CPA2-SQ and CPA3-8Q by GPC, Solubility, FT-IR and UV-vis absorption proved that the ingraft reaction is successful.
