Abstract

The invention relates to particle-comprising polyether alcohols which can be prepared by in-situ polymerization of olefinically unsaturated monomers in a polyether alcohol, wherein the polymerization is carried out in the presence of at least one compound (A) comprising a polysiloxane chain to which at least one polyether chain comprising at least one reactive hydrogen atom and a polyether chain comprising at least one olefinic double bond are bonded.
