폴리에테르 폴리올은 출발물 및 알킬렌 옥시드의 연속적 첨가를 포함하는 방법에 의해 제조된다. 출발물의 공급은, 알킬렌 옥시드의 80 내지 95%가 반응기에 공급되었을 때 중단된다. 이 방법은 좁은 분자량 분포를 갖는 생성물을 생성한다. Polyether polyols are made by a process that includes a continuous addition of starter and alkylene oxide. The feed of starter is discontinued when 80 to 95% of the alkylene oxide has been fed to the reactor. This process produces a product with a narrow molecular weight distribution.
