polyether alcohol, processes for the preparation of polyether alcohol and for the production of polyurethanes, polyurethane, and use of polyether alcohol

摘要

The invention relates to polyether alcohols which contain particles, can be produced by in-situ polymerization of olefinically unsaturated monomers in a polyether alcohol, and are characterized in that the polymerization process is carried out in the presence of at least one compound (A) containing a polyether siloxane chain on which at least one polyether chain containing at least one reactive hydrogen atom, and a polyether chain containing at least one olefinic double bond are located.
