摘　　要：A series of polymer-polyol dispersions have been prepared from polyether polyol and poly(styrene-acrylonitrile). The rheological behavior and particle size of the dispersions have been measured. The flow curves of the dispersions indicated the non-Newtonian behavior of shear thickening to shear thinning. The particle size in dispersions are affected by macromer content, temperature and stirring rate in preparation.A series of polymer-polyol dispersions have been prepared from polyether polyol and poly(styrene-acrylonitrile).
