Polyurethane foam prepared from a copolymer/polyol composition |
摘要 |
This invention relates to a novel process for producing polymer/polyols characterized by the use of specific amounts of particular monomer combinations and by maintaining a low monomer concentration throughout the reaction mixture during the process. The monomer combinations are acrylonitrile or methacrylonitrile and styrene or alpha-methyl styrene. The process produces novel polymer/polyols characterized by their convertibility to low density, water-blown polyurethane foams having reduced scorch and by the relatively small size of the polymer particles.
