- Method for separating partial methacrylated polyols and urethane-based materials functionalized with methacrylate produced by the partial methacrylated polyols

摘要

A method for separating a partial (meth)acrylated polyol of the present invention comprises the steps of: making a triol react with (meth)acrylate; firstly extracting by adding water to the partial (meth)acrylated polyol prepared from the reaction step; and secondly extracting by adding a solvent to a first aqueous phase which is separated from a first organic phase in the first extraction step. A urethane-based material functionalized with (meth)acrylate of the present invention can be prepared by the reaction of a partial (meth)acrylated polyol and isocyanate.
