Abstract
The present invention discloses a polymeric polyol composition useful for making polyurethane polymers, especially polyurethane foams. Said polyurethane polymer foams demonstrate a good balance of mechanical properties, physical properties, and low emissions. The polymeric polyol composition is the reaction product(s) of (i) a polyamine initiator composition comprising the polymerization product(s) of aminoethylpiperazine with (ii) at least one epoxide compound, at least one glycidyl ether compound, or mixtures thereof.
