ABSTRACT:
Provided is a process for preparing an at least bis-carbamate functional 1,3,5-triazine by contacting an at least diamino-1,3,5-triazine, an acyclic organic carbonate and a base, as well as certain novel compositions producible thereby. Also provided are substantially halogen contamination free crosslinker compositions comprising the products obtainable by the process, and curable compositions based upon these crosslinkers.
