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.

Claim 1
Independent Claim
211 words
A polyol having the general formula: ##STR7## wherein A and A 1 are individually connective atoms which may be the same or different and are selected from the group consisting of carbon and oxygen or combinations thereof; C is a carbon atom; Q is member selected from the group consisting of O, CH 2 O, C 2 H 4 O, C 3 H 6 O and C 4 H 8 O; D is a member selected from the group consisting of [C a H 2a O] ##STR8## where a has a value of one to four; H is hydrogen; R is selected from the group consisting of hydrogen, alkyl and aryl; X and X 1 may be the same or different and are individually selected from the group consisting of OH, NHR and H, X and X 1 being selected such that the combination of X and X 1 and their respective adjacent atomic units A and A 1 provide a functional group reactive with an isocyanate radical; n and d are individually intergers of 0 to 10 of which the sum of n and d is at least 1 and does not exceed 10; s is either 0 or 1; and m is an integer of at least about 16.
