실험 절차
About 348 parts of toluene diisocyanate are mixed with 90 parts of 1,3-butylene glycol and reacted at 30° C. to form a diurethane diisocyanate. About 260 parts of hydroxyethyl methacrylate are added to the resultant diurethane diisocyanate and the mixture heated at 50° C. until the --NCO content is zero.
후처리
- customreacted at 30° C.
