The present invention suggests a 2-oxo-1,3-dioxolane-4-carboxamide of formula (I), wherein R is an n-valent radical, n is an integer from 2 to 4, preferably from 2 to 3, and x is an integer from 1 to n-1. The invention furthermore suggests a process for the preparation of the 2-oxo-1,3-dioxolane-4-carboxamide of formula (I) from 2-oxo-1,3- dioxolane-4-carboxylic acid of formula (II), with a polyisocyanate of the formula R(NCO)n, where R and n have the meanings given, the use of the 2-oxo-1,3-dioxolane-4-carboxamide of formula (I) for the preparation of a 2-oxo-1,3-dioxolane-4-carboxamide-substituted prepolymer, and the 2-oxo-1,3-dioxolane-4-carboxamide-substituted prepolymer thus obtainable.
本发明提出了一种式(I)的2-氧代-1,3-二氧杂环戊酰胺,其中R是一个n价基团,n是一个整数,范围从2到4,最好从2到3,x是一个整数,范围从1到n-1。此外,本发明提出了一种从式(II)的2-氧代-1,3-二氧杂环戊酸通过式R(NCO)n的多异氰酸酯的制备方法,其中R和n具有给定的含义,以及使用式(I)的2-氧代-1,3-二氧杂环戊酰胺制备2-氧代-1,3-二氧杂环戊酰胺取代预聚合物,以及由此获得的2-氧代-1,3-二氧杂环戊酰胺取代预聚合物。
