HCID 86739092Diisocyanate Diurethane

Procedure

About 348 parts of toluene diisocyanate are mixed with 62 parts of ethylene glycol and reacted at room temperature (25° C.) to form a diurethane diisocyanate. About 260 parts of hydroxyethyl methacrylate are added to the resultant diurethane diisocyanate and the mixture heated to about 80° C. for about 3 hours.

Workup

customreacted at room temperature (25° C.)
