Abstract
Official abstract text for this publication.
Disclosed is a process for the preparation of polyetherester polyols prepared with hybrid catalysts, the polyetheresters obtained from the process and the use of such materials in polyurethane applications. The hybrid catalysts used in this invention comprise double metal cyanide complex catalysts (DMC) and at least one co-catalyst.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for synthesizing a polyetherester polyol, the process comprising copolymerizing an alkylene oxide with carbon dioxide, a cyclic compound of the following formula or both, in the presence of an initiator and a hybrid catalyst, wherein the hybrid catalyst comprises a double metal cyanide complex catalyst and a co-catalyst, the co-…
