摘　　要：在氢氧化钠催化条件下,利用缩水甘油三甲基氯化铵(GTA)对端羟基超支化聚酯Boltorn H20进行季铵化改性,得到了超支化聚酯季铵盐GTA-H20,研究了反应条件对产率的影响,结果表明:当n(H20)∶n(GTA)=1∶16,n(NaOH)/n(H20-OH)=0.5,50℃反应24h,产率为61.11%.元素分析结果表明:此时GTA的取代度为22.32%,并用1H NMR、FT-IR和13C NMR谱图对GTA-H20进行了表征.In the presence of alkaline catalyst sodium hydroxide, quaternary ammonium salt of hyperbranched polyester （GTA-H20） was prepared by the modification of hyperbranched polyester Boltorn H20 with gly- cidyltrimethylammonium chloride （GTA）. The influences of reaction conditions on the yield of product were studied. The results showed that under the conditions of n（H20）：n（GTA）=1：16, n（NaOH）/n（H20-OH）=0.5, 50 ~C of reaction temperature and 24 h of reaction time, the product 61.11% of yield was obtained. The element analysis indicated that the substitution degree of GTA was 22.32%, and the structure of the product was characterized by 1H NMR, FT-IR and 13C NMR.
