Isocyanates derived from dienes and process and their preparation.

摘要

A process is disclosed for the preparation of novel wholly aliphatic mono- and diisocyanates by thermal fracturing diurethanes that have been prepared by acid-catalyzed addition of alkyl carbamates to olefinic compounds, especially dienes. The compounds can be modified or used per se to produce curable compositions, e.g., with polyols.
