LOW DIOL CONTENT MONOFUNCTIONAL ALKOXYPOLYALKYLENE GLYCOLS AND PROCESS FOR PRODUCING THEM

摘要

Provided is a process for preparing low diol content monofunctional polyalkylene glycols. The process includes introducing the initiator feed in two portions (a first and second initiator) and drying only the first initiator to remove water. The first and second initiators can be the same or different. Also provided are new monofunctional polyalkylene glycol compositions.
