专利号:WO-2014118073-A1 优先权日:2013-01-29 标 题 :Polysulfide polyols, their production and use in the synthesis of polyurethanes 发明人:BALBO BLOCK MARCO; RHUDY KEVIN; FLECKENSTEIN CHRISTOPH 权利人:BASF SE 摘要:The present invention relates to sulfur containing polyols, a process for their production by reaction of at least one unsaturated alcohol A with elemental sulfur, wherein the unsaturated alcohol A has only one carbon-carbon double bond-unsaturation per molecule. The sulfur containing polyols are used in the production of polyurethanes, in particular rigid foam polyurethanes, for high-temperature pipe insulation applications.
