本文对邻苯二甲酸酐、顺丁烯二酸酐和乙二醇的缩聚反应速度常数进行了测定,确定了两种酸酐在不同温度下对乙二醇的兢聚率,为合成较均一的(无规的)链节分布提供了合理的缩聚反应条件。
In this paper, the polycondensation reaction rate constants of phthalic anhydride, maleic anhydride and ethylene glycol were determined, the two kinds of anhydride at different temperatures to determine the concentration of ethylene glycol, for the synthesis of more uniform ( Random) chain segment distribution provides a reasonable polycondensation reaction conditions.
