Polyethers having terminal allyl unsaturation are Subject to hydrogenolysis by reaction with a hydrogen donor in the presence of a hydrogenolysis forming catalyst. The product polyethers have extremely low levels of unsaturation, and thus are useful in preparing polyurethanes having improved properties and processing.
具有末端烯丙基不饱和度的聚醚在氢解催化剂的作用下,通过与氢供体反应进行氢解。生成的聚醚具有极低的不饱和度,因此可用于制备具有更好性能和加工性能的聚
