ABSTRACT:
The instant invention is directed to novel polyols and the use thereof in producing polyurethane foams. The polyols comprise the adduct obtained by first reacting toluene diamine with from three to five moles of ethylene oxide and thereafter with from 1 to 5.1 moles (per mole of toluene diamine) of a vicinal alkylene oxide of from 3 to 9 carbon atoms, with the proviso that the total number of moles of ethylene oxide plus vicinal alkylene oxide does not exceed 8.1 and is no less than 5. When polyurethane foams are produced using the novel polyols herein, foams of low friability and good dimensional stability result.
