Isocyanato-acylurethanes, a process for their preparation and their use

摘要

The present invention relates to isocyanto-acylurethanes corresponding to Formula I <IMAGE> (I) wherein R has a valency of m+n and is a hydrocarbon group, R' is a hydrocarbon group and m and n may be identical or different, and each have a value of 1 or 2. The present invention also relates to a process for preparation of these isocyanato-acylurethanes which comprises reacting isocyanato-carboxylic acid chlorides with carbamic acid esters. Finally, the present invention is directed to the use of these isocyanato-acylurethanes as intermediate products for the production of thermally cross-linkable synthetic resins or synthetic resin precursors and also as intermediate products for the preparation of cross-linking agents for synthetic resins.
