Abstract
Abstract Novel polyols, useful in, for example, reaction injection molding, high resiliency foams and the preparation of polymer/polyols, characterized by the following formula: <IMAGE> wherein A and A', which may be the same or different, are conductive 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, CH2O, C2H4O, C3H6O, or C4H8O; D is an oxyalkylene or <IMAGE> X and X', which may be the same or different, are OH, NH2 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.
