Title: (EN) Method for producing a storage-stable and colorless liquid polyisocyanate composition possessing carbodiimide and/or uretonimine groups
(ZH) 制备贮存稳定的且含有碳二亚胺和/或脲酮亚胺基团的无色液态聚异氰酸酯组合物的方法
Abstract:
(EN) Method for producing a storage-stable and colorless liquid polyisocyanate composition possessing carbodiimide and/or uretonimine groups comprising the steps of a) condensing a polyisocyanate in the presence of a catalyst selected from the group consisting of phospholenes, phospholidines and/or their oxides, and b) stopping the condensation by adding adipoylchloride as catalyst killer.
(ZH)

一种制备贮存稳定的且含有碳二亚胺和/或脲酮亚胺基团的无色液态聚异氰酸酯组合物的方法,包括如下步骤:a)在选自环磷烯、磷啶和/或其氧化物的催化剂的存在下将聚异氰酸酯进行缩合,以及b)加入催化剂抑制剂己二酰二氯以终止缩合。
