    摘要: A process for producing hyperbranched, dendritic polyglycerol from glycerol comprising the steps of adding in a vessel glycerol and a CaO-based catalyst, flushing an inert gas to the resulting mixture and hermetically closing the reaction vessel, allowing pressure to build up from 1 to 10 bar above atmospheric, and heating the reaction mixture at a reaction temperature of at least 100° C. and below its boiling point. The process further comprising the steps of maintaining the reaction conditions until at least 40 wt. % of glycerol is polycondensed and converted into hyperbranched polyglycerol, with concomitant water formation, and separating the dendritic polyglycerol from other components in the mixture. The calcium based catalyst is nanostructured calcium oxide in the form of a powder of mean particle size smaller than 100 nm measured according to ASTM D4464.

    摘要: An object of the invention is to provide resin premix compositions which include a polyol and a hydrocarbon foaming agent while still exhibiting good storage stability, the polyol being obtained without the use of ring-opening polymerization reaction of a cyclic ether. The resin premix composition of the invention includes at least a polyol and a hydrocarbon foaming agent, the polyol including a polyether ester polyol (A) obtained by reacting a polyether polyol with a fatty acid and/or a fatty acid ester, the polyether polyol being obtained by condensing a polyhydric alcohol including 50 mol % or more of a trihydric or higher alcohol.
