POLYAMINOL AND ADHESIVE SYNTHESIZED THEREFROM

摘要

PURPOSE: A polyaminol and an adhesive synthesized therefrom are provided to increase the number of urethane bond by inducing 3 hydroxyl groups instead of 2 hydroxyl groups per a double bond by a secondary aminol. CONSTITUTION: A polyaminol is represented by chemical formula 1. In chemical formula 1, R1 and R2 are H or [CH2]n-OH; and n is an integer of 1-20. The polyaminol is synthesized from the oil selected from the group consisting of cooking oil and vegetable oil. A method for preparing comprises the steps of epoxidizing vegetable oil; synthesizing the polyaminol from the epoxidized vegetable oil; and mixing the prepared polyaminol and polymethylene bisphenylisocyanate(PMDI).
