Simultaneous Determination of Number Average Relative Molecular Mass,Viscosity and Hydroxyl Value for Hydroxyl-terminated Polybutadiene by Near-Infrared Spectroscopy

Number average relative molecular mass,viscosity and hydroxyl value of hydroxyl-terminated polybutadiene(HTPB) were simultaneously measured by near-infrared spectroscopy.Compared to conventional methods,the satisfied results can be obtained.This method can be used in HTPB industrial production as a simple and rapid quantitative analysis method.
