Abstract Selected phosphorus compounds, carbonyl compounds and alkanolamines are reacted to produce compounds of the formula: WHEREIN M AND N ARE ZERO TO TWO AND M + N EQUALS TWO; A IS ZERO TO 1, B IS 1 TO 2 AND A + B EQUALS 2; X is oxygen or sulfur; R1, R2, R3, and R4 are organic radicals and R3 and R4 can also be hydrogen, and R5 is an alkyl group. Such compounds can be reacted with carboxylic compounds to produce polyesters, or with epoxides to form polyethers. Such polyesters and polyethers, as well as the compounds themselves, can be reacted with isocyanates to produce polyurethane compositions. When the reaction is carried out in the presence of a foaming agent, cellular products are produced.
The polyester of claim 1 wherein the phosphorus compound has the formula:

an hydroxyl terminated polyester which is the reaction product of A. a polycarboxylic compound selected from the group consisting of di- and tricarboxylic acids, di- and tricarboxylic acid halides, di- and tricarboxylic acid anhydrides and mixtures thereof and B. a polyol selected from the group consisting of open chain aliphatic polyhydric alcohols and polyalkylene ether polyols possessing from 2-6 esterifiable hydroxyl groups and containing up to 20 carbon atoms.
