TMP选择烯丙醚化及PE气干型改性

TRIMETHYLOLPROPANE SELECTED ALLYL ETHERIZATION AND POLYESTER MODIFIED AIR-DRYING

本文研究三羟甲基丙烷（ＴＭＰ）单烯丙醚（ＭＡＴＭＰ）、双烯丙醚（ＤＡＴＭＰ）的合成方法及其在不饱和聚酯（ＰＥ）气干型改性应用。当选择５％摩尔量的四丁基溴化铵（ＴＢＡＢ）作相转移催化剂。５０％ＮａＯＨ，反应温度９０℃，无溶剂的条件时，产物含２１．３％ＭＡＴＭＰ、７３．８％ＤＡＴＭＰ和４．９％三羟甲基丙烷三烯丙醚（ＴＡＴＭＰ），总收率为８４．５％。该产物用于ＰＥ树脂气干型改性，能抗空气中氧的阻聚作用。

synthesis method of monoallylether or diallylether of trimethylolpropane(MATMP , DATMP)and the product for lnedifed air-drying unsaturated polyester are studied in this article. Selecting5%mol. tetrabutyl ammonium bromide of phase transfer catalyst, 50%NaOH ,reactive tempera-ture 90℃,non-solvent,the preduct contains MATMP 21.3%,DATMP 73.8%, triallyl-ether-trimethylolpropane(TATMP)4.9%, Total yield is 84.5%.The air-drying unsaturatedpolyester resin prepared by using the preduct can avoid the inherit polymerization of atmosphericoxygen.At the same time,a way for reducing reactive time on synthesis PE and the factor of ef-fect on air-drying property,hardness of the resin film has been discussed.
