Vinyl polymer polyols made using partially alkoxylated polyoxyalkyleneamines

A vinyl polymer polyol which provides faster curing polyurethane foams with improved load bearing properties, prepared by the process comprising polymerizing via a free radical initiated reaction a vinyl monomer component consisting of styrene and acrylonitrile in the presence of a partially alkoxylated polyoxyalkyleneamine having a 2,000 to 8,000 molecular weight and containing both --NH.sub.2 and --OH groups, in which the polymer loading of the partially alkoxylated polyoxyalkyleneamine is in the range of about 5 to 50 wt. %.

A vinyl polymer polyol prepared by the process which comprises polymerizing via a free radical initiated reaction a vinyl monomer component consisting of styrene and acrylonitrile in a weight ratio ranging from 9:1 to 1:9, using a partially alkoxylated polyoxyalkyleneamine having a 2,000 to 8,000 molecular weight and containing both --NH.sub.2 and --OH groups as the dispersing media, at a temperature in the range of 75.degree. to 150.degree. C. and a pressure in the range of atmospheric to about 100 psig, to give a vinyl polymer polyol with a polymer loading in the range of 5 to 50% and which provides faster curing polyurethane foams with improved load bearing properties.
