The present invention discloses a tertiary amine initiator and polymeric polyol compositions made therefrom 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 tertiary amine initiator is one or more partially alkylated amine compound have the Structure II: RR 1 N - (R'-NH) y - (R'-NR 4 ) x-y - R' - NR 2 R 3 wherein R' is a C 1 to C 6 linear or branched alkyl group, R, R 1 , R 2 , and R 3 are independently a hydrogen or a C 1 to C 6 linear or branched alkyl group with the proviso that at least one of R, R 1 , R 2 , and R 3 is not hydrogen, R 4 is a hydrogen or a C 1 to C 6 linear or branched alkyl group, x is from 1 to 33, y is from 0 to 32, and z is from 0 to 15, with the proviso that x-y is equal to or greater than 1 and the number of N-H bonds in (II) is greater than 0 and less than 8.
