Stabilized, finely disperse low-viscosity polymer polyols with a high content of polystyrene or polystyrene copolymers

摘要

The present invention relates to finely dispersed, low-viscosity polymer polyols which are stabilized in a novel manner and which are characterized by a high content of polystyrene or polystyrene copolymers. This invention also relates to the preparation of such polymer polyols, and their use for the preparation of polyurethane materials.
