히드록실 기가 56 이하이고, 높은 평균 관능성 및 높은 일급 히드록시 함량을 특징으로 하는 폴리에테르 디올은 불포화 알콜을 다중 단계로 알콕시화하여 39 % 이상의 일급 히드록실 기를 함유하는 폴리에테르 모노올을 형성한 후 상기 폴리에테르 모노올을 일급 히드록실 기를 갖는 머캅토 알코올과 반응시켜 제조된다. Polyether diols characterized by a hydroxyl number of 56 or lower, high average functionality and high primary hydroxyl content are prepared by alkoxylating an unsaturated alcohol in multiple steps to form a polyether monol that contains 39% or more primary hydroxyl groups, and then reacting the polyether monol with a mercaptoalcohol that has a primary hydroxyl group.
