초록

N-methyl-2-pyrrolidone(NMP) 용매하에서 dibutyltin dilaurate(DBT)를 촉매로, 50℃∼80℃ 범위에서 methylene bis(4-cyclohexyl isocyanate) (H₁₂MDI)와 polyhexamethylene carbonate glycol(PHC), polytetramethylene adipate glycol(PTAd) 및 polypropylene glycol(PPG)과의 반응을 행하여 이들 반응의 속도상수 및 활성화 에너지를 구하였다. 또한 특정 모델 반응에 대하여 [NCO]/[OH]비. polyol의 분자량, 촉매의 종류 및 함량이 반응에 미치는 영향을 검토하였다.

Basic kinetic data of reactions between methylene bits(4-cyclohexyl isocyanate) (H₁₂MDI) and polyhexamethytene carbonate glycol(PHC), polytetramethylene adipate glycol(PTAd), and polypropylene glycol(PPG) in N-methyl-2-pyrrolidone (NMP) with dibutyltin dilaurate(DBT) catalyst were obtained at 50∼80℃ The effects of [NCO]/[OH] ratio. molecular weight of polyol, catalyst type and amount were examined from specific model reactions.
