Polymer polyols KYH-2045 which are based on general polyether polyols are synthesized by free radical graft polymerization with initiator and monomers of styrene and acrylonitrile under specific temperature and nitrogen protection. They  are characterized by BHT free, low monomer residues, low viscosity and high solid content at 44.5%~48.5%, They gives a good flowabitily when mixing with water. The foam made by the products has low density gradient and uniform and fine cell structure. The products are mainly used in the high hardness flexible slabstock foams and flame lamination foams.
