Characterization of Phenolic Resin Containning Tungsten by High Performance Liquid Chromatography and Gel Permeation Chromatography
高效液相色谱法和凝胶色谱法对钨酚醛树脂的表征

he properties of phenolic resin containning tungsten(WP-F in different polymerization stages arecharacterized by using high Performance liquid chromatography and gel permeation chromatography. Depending on the changes of the polarity and molecular weight of system,the controlling stage is found out,and thebehavior of the compound containing tungsten to the polymerization is studied.
