| 摘要 |
A process for the production of a fluid polymer polyol containing (a) greater than 30% by weight polymer and/or (b) a poly(acrylonitrile/styrene) copolymer comprising between 65 and 90% by weight polystyrene is provided. By using a peroxydicarbonate catalyst during the process products of improved viscosity and filtrability are produced.
