ABSTRACT:
The instant invention is directed to a process for the preparation of modified polyether polyols comprising polymerizing of from 1 to 50 parts by weight of a mixture of 20 to 100% by weight (based on the total quantity of monomers) of acrylonitrile and 0 to 80% by weight of styrene in 50 to 99 parts by weight of the polyether polyol in the presence of a polymerization initiator which yields radicals, wherein said polymerization is carried out in the presence of from 0.1 to 1.5% by weight, based on the total quantity of monomers put into the process, of a compound of the formula:
