摘要
the present invention is preparing a polytetramethylene ether glycol (PTMEG) of the narrow molecular weight distribution It provides an improved method for. The product is polytetramethylene ether glycol of the feedstock corresponding polytetramethylene ether glycol and the number average molecular weight increase in comparison, lower polydispersity, and has a reduced molecular weight ratio.
