KINETIC ANALYSIS OF STAR COUPLING REACTION
星形偶联反应的动力学分析

A kinetic analysis of star coupling reaction of living polymers has been carried out. The molecular weight distribution function and some molecular parameters of the pre-polymers are concerened in those of prepolymers. The conclusions obtained include that the more arms the star polymer has, the more homogenious is it; when the degree of branching is large enough, the star polymer follows the normal distribution inspite of the dispersity of prepolymer.
