Abstract: Branched polyglycols and branched polyether functional organopolysiloxanes are disclosed as is a process for making branched polyether functional organopolysiloxanes by reacting an organohydrogensiloxane and a branched polyglycol having an unsaturated group via a hydrosilylation reaction, as well as coating compositions containing branched polyether functional organopolysiloxanes and a binder are disclosed. Coatings resulting from these compositions were more hydrophilic and had improved dirt release properties as compared to coatings containing similar, but un-branched, polyether functional organopolysiloxanes.

Abstract: 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.

Abstract: Certain alcohol initiators containing halogen, aldehyde, ketone or nitro substitution can be alkoxylated with excellent efficiency and low production of by-products using an metal cyanide catalyst. The products contain halogen, aldehyde, ketone or nitro groups that can undergo subsequent reactions to form amino groups.

Abstract: Ethoxylations of various initiator compounds are performed in the presence of metal cyanide catalysts. The catalysts surprisingly form a wide variety of polyether products that in most cases contain only small amounts of high molecular weight poly(ethylene oxide).
