This invention relates to polybutadiene modified polymer polyols which comprise one or more base polyols, at least one preformed stabilizer, one or more ethylenically unsaturated monomers, and polybutadiene, in the presence of at least one free radical polymerization catalyst, and optionally, one or more chain transfer agents. The electromagnetic noise absorber comprises a strip-like base material and a plurality of ferrite pieces fixed to the strip-like base material. Also provided by the invention are tissue cultures of the soybean variety A1016279 and the plants regenerated therefrom.
