Abstract
The subject invention relates to polyol compositions which are alkylene oxide adducts of a mixture of initiators comprising vicinal toluenediamine and an initiator selected from the group consisting of ammonia, an aliphatic amine having a molecular weight of from 20 to 120, an alkanolamine having a molecular weight of from 50 to 120, and mixtures thereof. Low molecular weight diols may also be used as a co-initiator in combination with ammonia, an aliphatic amine, an alkanolamine, or mixtures thereof. The subject polyol compositions are particularly useful in the preparation of rigid polyurethane foams.
