| description | PROBLEM TO BE SOLVED: To provide an analytical method capable of quantitating accurately even a trace remaining hydroxyl body and quantitating simultaneously an impurity having a different molecular weight, concerning a method for determining the reaction rate in a reaction wherein a polymer compound having a hydroxy group on the terminal is used as a raw material and a functional group not reacting with isocyanate is introduced onto the terminal. SOLUTION: A remaining terminal hydroxy group-containing polymer compound is quantitated by using a liquid chromatography using a GPC column, in the reaction wherein the polymer compound having the hydroxy group on the terminal and having the molecular weight of 1,000-100,000 is used as the raw material and the functional group not reacting with isocyanate is introduced into the terminal. This method is characterized by determining hereby the reaction rate of a functional group introduction reaction product. COPYRIGHT: (C)2004,JPO&NCIPI |
