Process for production of polymer polyol, and polymer polyol |
摘要 |
A polymer polyol comprising 25 to 60 mass % polyol (A) and 40 to 75 mass % of polymer particles (B1) formed by polymerizing ethylenically unsaturated monomer in the polyol (A), the ethylenically unsaturated monomer having the content of acrylonitrile and/or styrene is not less than 50 mass %, wherein (B1) has a particle size of not more than 100 mum and contains not less than 95 mass % of particles with the particle size of 0.01 to 10 mum; and the total content of acrylonitrile and styrene is not more than 20 ppm; and process for producing the polymer polyol. The polymer polyol exhibits a reduced residual monomer content and excellent filtration property and is useful as a raw material in the production of polyurethane or the like.
