The present invention relates to a dimeric urethane compounds derived from monohydric alcohols, generally fatty alcohols, and a diisocyanate according to the following reaction scheme:
wherein R1 is selected from the group of saturated, unsaturated or halogen substituted linear, cyclic or branch-chained hydrocarbons and R2 is a linear, cyclic or branch-chained alkyl or aminoalkyl group ranging from two to 200 carbon atoms, preferably two to 50 carbons, more preferably 6 to 36 carbons, said urethane compound being substantially free from terminal hydroxyl groups.
本发明涉及从单元醇(通常为脂肪醇)和二异氰酸酯衍生的二聚脲醇化合物,其反应方案如下:其中R1选自饱和、不饱和或卤素取代的直链、环状或支链烃基,R2是直链、环状或支链烷基或氨基烷基,碳原子数范围为2至200,优选为2至50个碳原子,更优选为6至36个碳原子,所述脲醇化合物基本上不含末端羟基。
