Peg and superfluous aa reaction by complete concatenation method , the esterify production “ esterify water “ and acid number were mensurated , it shows that the esterify reaction would be processed under 100 esterify temperature and with amine accelerantthe tide of esterify reaction was substantiated by ir . in the ir spectrum , the characteristic peak of hydroxy of peg and carboxyl of aa were weakened . and the ester link of peg was reinforce . the “ esterify water “ was increased gradually and the acid number of esterify production was debased gradually along with the extent of esterify time and the augmentation of molecular weight of peg 通過聚乙二醇與過量的丙烯酸采用全連續法進行反應，測定酯化產物“酯化水”和酸值等宏觀手段反映出在胺類促進劑、 100的酯化溫度等條件下的酯化進程，而利用紅外光譜( ir )分析所反映的聚乙二醇的羥基和丙烯酸的羧基特征峰減弱，而pea的酯基特征峰加強等特征進一步證實了宏觀手段所表現出來的酯化趨勢：隨著酯化時間的延長和聚乙二醇分子量的增大，產生的“酯化水”逐漸增加，酯化產物的酸值逐漸降低；從酯化時間看，當反應時間達到300min時，酯化物的酸值達到最小，而從ir分析來看，酯化物pea4的羥基峰在300min時減弱到最小， pea23在120min時羥基峰的表現出酯化基本完全。

When the reaction time was soomin , the acid number of esterify production was least . it shows that hydroxy peak of pea4 would be least at 300min , the hydroxy peak of pea23 was almost disappeared at 120min . in macroscopical side , the acid number can only indicate that superflous aa was reduced along with esterify reaction and pumping water 因此，宏觀手段和微結構表征表現的酯化反應趨勢是一致的，而宏觀上的酸值只能反應過量丙烯酸的隨著酯化反應和除水作用而減少，并不能完全真實反映酯化進程，而微觀上進一步證實了不同分子量的聚乙二醇的酯化所需的酯化時間隨著分子量的增大而減少。
