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.

Dependent claims

A method for producing a polyurethane by reacting a mixture comprising (a) a polyol having the following formula:

##STR12## wherein A and A' 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;
R is selected from the group consisting of hydrogen, alkyl and aryl;
Q is a member selected from the group consisting of O, CH.sub.2 O, C.sub.2 H.sub.4 O, C.sub.3 H.sub.6 O and C.sub.4 H.sub.8 O;
D is a member selected from the group consisting of --OC.sub.a H.sub.2a -- and ##STR13## where a has a value of one to four;
X and X', may be the same or different, and are individually members selected from the group consisting of OH, NHR and H, X and X' being selected such that the combination of X and X' and their respective adjacent atomic units A and A' provide a functional group reactive with an isocyanate radical;
n and d are individually integers of 0 and 10 and the sum of n and d is at least one and does not exceed 10;
s is either 0 or 1, and m is an integer of at least about 16, (b) an organic polyisocyanate and (c) a catalyst for the reaction of (a) and (b).
