摘要：
A polymeric stabilizer is produced by copolymerizing an unsaturated polyether with an unsaturated low molecular weight monomer in a controlled radical polymerization. The polymeric stabilizer is useful for producing polymer polyol products via a mechanical dispersion process or an in situ polymerization process.
