Abstract

A polyether polyols contains an equivalent of 500 to 10,000 and an mean functionality of 2 to 8, and each polybond comprises AOR block and EOR block having 3-4 carbon atoms, in which the AOR block containing 100-5 weight % of 1,4- BOR; for each weight of AOR block and EOR block, the AOR block weight is 70-95 weight % and EOR block weight is 5-30 weight % and the EOR is the terminal of the polybond.
