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.
本发明提供了一种通过至少二氨基-1,3,5-三嗪、无环有机碳酸盐和碱的接触来制备至少双氨基甲酸酯官能团的 1,3,5-三嗪的工艺,以及可通过该工艺制备的某些新型组合物。此外,还提供了基本上不含卤素污染的交联剂组合物,其中包括通过该工艺可获得的产物,以及基于这些交联剂的可固化组合物。
