摘要： A flexibilizing capped prepolymer can include a reaction product of reaction mixture including a polyisocyanate and an isocyanate-reactive component at an equivalent ratio of polyisocyanate equivalents to isocyanate-reactive component equivalents of from 1.4:1 to 2.1:1. The isocyanate-reactive component can include a polyol component and a branching agent component. The branching agent component can include a monoglyceride, a diglyceride, a triglyceride, or a combination thereof having a number average functionality of from 3 to 6 NCO-reactive functional groups. The reaction product is terminated with a capping agent to form the flexibilizing capped prepolymer.

摘要： Processes and production plants for preparing a polyol. The process includes continuously producing an intermediate polyol in a first reactor, b) continuously discharging the intermediate polyol from the first reactor, continuously mixing the intermediate polyol with an aqueous solutions of alkali metal to provide a mixture comprising the intermediate polyol, alkali metal, and water, continuously dehydrating the mixture comprising intermediate polyol, alkali metal, and water, thereby continuously producing a dehydrated mixture comprising the intermediate polyol and the alkali metal, transferring the dehydrated mixture to a second reactor, and producing the polyether polyol in the second reactor by feeding an alkylene oxide to the second reactor to thereby react the intermediate polyol with the alkylene oxide in the presence of the alkali metal.

摘要： This invention relates to a process for preparing low viscosity polyoxyalkylene polyols (P) that have a narrow molecular weight distribution. This process comprises reacting a H-functional starter substance (Si), a H-functional starter substance (Sx) and a H-functional starter substance (Sc) with one or more alkylene oxides in the presence of a double metal cyanide catalyst. The resultant polyoxyalkylene polyols (P) have a functionality of 2 to 8 and a hydroxyl number of 5 to 35 mg KOH/g polyol.
