影响TDI-TMP加成反应的因素

FACTORS INFLUENCING THE ADDITION REACTION OF TDI-TMP

围绕着提高甲苯二异氰酸酯－三羟甲基丙烷（ＴＤＩ－ＴＭＰ）加成物的性能水平，通过实验着重介绍和探讨了影响ＴＤＩ－ＴＭＰ加成反应的几个重要因素，如温度、溶剂、加料方式、ＮＣＯ／ＯＨ比以及多元醇的变化等。要提高ＴＤＩ－ＴＭＰ的内在品质。

For improving the performance of TDI-TMP adduct,this article is focused on discussion of the factors influencing the TDI-TMP addition reaction,such as temperature,solvents,charging methods,NCO/OH ration and polyols It is necessary to emphasize the importance of after-treatment for improving the quality of TDI-TMP
