POLYASPARTIC ACID ESTER COMPOSITIONS CONTAINING POLYASPARTIC ACID ESTER WITH PRIMARY AMINO GROUPS AND SMALL AMOUNTS OF FUMARIC ACID DIALKYL ESTER

摘要

The present invention relates to polyaspraginate ester compositions comprising polyaspartic acid esters having primary amino groups and small amounts of dialkyl fumarates, a process for their preparation and their use as reactive components for polyisocyanates in two-component polyurethane systems.
