ABSTRACT:
Novel polyols, useful in, for example, reaction injection molding, high resiliency foams and the preparation of polymer/polyols, characterized by the following formula: ##STR1## wherein A and A', which may be the same or different, are connective atoms--carbon, oxygen or combinations thereof with hydrogen atoms or the like satisfying the valences; B is nitrogen (N) or CR, R being hydrogen, alkyl, aryl or the like; Q is 0, CH.sub.2 O, C.sub.2 H.sub.4 O, C.sub.3 H.sub.6 O, or C.sub.4 H.sub.8 O; D is an oxyalkylene or ##STR2## X and X', which may be the same or different, are OH, NH.sub.2 or H; Z is OH; n and d are integers of 0 to 10 and the sum of n and d does not exceed 10; s is 0 or 1, and m is an integer of at least about 16, with the proviso that when B is N and either n or d is zero, X and X' are other than H, provide processing advantages and are highly compatible with low molecular weight extenders such as ethylene glycol.
