Abstract
Isocyante terminated urethane prepolymers were synthesized by the reaction of 4,4'-dimethyl phenyldiisocyanate(MDI) and ester type polyols such as ethylene glycol/ butanediol adipate(EBA), neopentylglycol/butanediol adipate (NBA) and hexanediol adipate (HA) . All of the NCO-terminated urethane prepolymers are solid at room temperature, but they become mobile enough to be disposed onto a substrate upon heating about
MDI와 에스테르타입의 폴리올인 EBA, NBA, HA를 각각 반응시켜 이소시아네이트 말단기를 갖는 다양한 우레탄 프리폴리머를 합성하였다. 합성된 프리폴리머는 상온에서는 100% 고형분이었으며, 약
