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

摘要

The separation method of the partial (meth)acrylated polyol of the present invention comprises the steps of reacting a triol and (meth)acrylate; Primary extraction by adding water to the partial (meth)acrylated polyol prepared from the reacting step; And in the first extraction step, a first organic phase and a first aqueous phase are separated, and a second extraction is performed by adding a solvent to the aqueous phase. The urethane-based material functionalized with (meth)acrylate of the present invention can be prepared by reaction with a partial (meth)acrylated polyol and isocyanate.
