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.
Claims16
A carbamate functional 1,3,5-triazine of the general formula ##STR13## wherein Z' is selected from the group consisting of hydrogen, hydrocarbyl, and a group represented by the formula NHQ',
- each Q' is independently selected from the group consisting of a hydrocarbyl, a hydrocarbyloxy hydrocarbyl and a group represented by the formula COOY, with the proviso that at least two of the Q' groups are COOY, and
- each Y is independently selected from the group consisting of a hydrocarbyl group and a hydrocarbyloxy hydrocarbyl ether group, with the proviso that at least one Y group is a hydrocarbyloxy hydrocarbyl ether group.
