Patent

CA 2497526

The present invention provides a process for preparing a polymer polyol (PMPO) by alkoxylating a starter compound(s) having active hydrogen atoms in the presence of a double metal cyanide (DMC) catalyst, radical initiator(s) and optionally PMPO stabilizers and simultaneously polymerizing unsaturated monomer(s) with radical initiator(s). The polymer polyols (PMPOs) made by the inventive process may find use in the preparation of polyurethane foams and elastomers.
