ABSTRACT:
Polymer polyols prepared by a semi-batch process using a small amount of a seed polymer polyol are disclosed. The final polymer polyol has a broader particle size distribution as compared to an identically prepared polymer polyol prepared in the absence of the seed polymer polyol. The polymer polyols are suitable for use in producing polyurethanes, particularly polyurethane foams.
