More Information
Summary:Acidification, neutralization, or removal of basic impurities from acid sensitive low molecular weight starter or acidification of a reactor heel prior to addition of acid sensitive low molecular weight starter allows direct oxyalkylation of continuously added acid sensitive low molecular weight starter to produce polyoxyalkylene acid sensitive low molecular weight starter-initiated or co-initiated polyols in the presence of a double metal cyanide catalyst. The preferred acid sensitive low molecular weight starter is glycerine.
