The invention concerns a process for preparing an N-substituted carbamoyl-lactam compound having the formula
by reactively admixing a polyhydroxy compound having the formula R(OH)n and a polyisocyanate having the formula OCN-R'-NCO, wherein said n is an integer a 3,
R is the residual of a three or higher functional polyhydroxy compound,
R' is an alkyl, aryl, alkaryl, or an aralkyl group having 6-25 carbon atoms, and Y is a C3-C14 alkylene group and reacting the product thereof with at least one lactam.
The product prepared accordingly can advantageously be used in the preparation of nylonblockcopolymers, and more in particular in the reaction injection moulding of nylon.
本发明涉及一种制备 N-取代氨基甲酰基内酰胺化合物的工艺,其式如下
将具有式 R(OH)n的多羟基化合物与具有式 OCN-R'-NCO 的多异氰酸酯反应混合,其中所述 n 为 3 的整数、
R 是三官能团或更高官能团的多羟基化合物的残余物、
R' 是具有 6-25 个碳原子的烷基、芳基、烷芳基或芳烷基,Y 是 C3-C14 亚烷基,并将其产物与至少一种内酰胺反应。
由此制备的产品可用于制备尼龙嵌段聚合物,尤其是用于尼龙的反应注塑成型。
