ABSTRACT:
Polyethers having terminal allyl unsaturation are subject to hydrogenolysis by reaction with a hydrogen donor in the presence of a n-allyl complex forming catalyst. The product polyethers have extremely low levels of unsaturation, and thus are useful in preparing polyurethanes having improved properties and processing.
