Title:

Building block of 2-oxo-1,3-dioxolane-4-carboxamide, its manufacture and use

Document Type and Number:

Japanese Patent JP6338599

Kind Code:

B2

Abstract:

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 10 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, and 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.
