Abstract

The present invention relates to ethylenically unsaturated macromonomers containing reactive unsaturated bonds and to methods for the preparation of these ethylenically unsaturated macromonomers containing reactive unsaturated bonds. These ethylenically unsaturated macromonomers are prepared by reacting a monofunctional compound conforming to a specific chemical formula with at least one alkylene oxide in the presence of at least one alkoxylation catalyst. The ethylenically unsaturated macromonomers conform to the chemical formulas described herein. The present invention also relates to preformed stabilizers comprising ethylenically unsaturated macromonomers, to processes for the preparation of these preformed stabilizers, to polymer polyols comprising these preformed stabilizers, and to these polymerizations comprising said preformed stabilizers. Preparation method of polyol. Polymer polyols containing ethylenically unsaturated macromonomers and methods for their preparation are also described.
