摘　　要：首次提出了均聚物的溶解度参数（δ）与共聚过程中Ｐｒｉｃｅ的共聚前置因子（Ｑ）和极性因子（ｅ）之间的相关性。其中ｅ和δ之间有良好的线性关系。从这里可以看出，决定共聚高分子链的序列均匀性（Ｒ１·Ｒ２）是在共聚反应的微观场合中，同类似于共聚高分子链式的过渡态有密切的关系。考察了ＰｒｉｃｅＱ值与单体定域能间关系，从中看出，除了丙烯腈单体以外，所有典型单体的Ｑ值与定域能间有良好的同步关系。In this paper, the relationship between solubility parameter (δ) of homopolymer and Q, e  in copolymerization was first investigated. There is a good linear relation between δ and e. From this , it can be seen what determine the degree of sequence (R1·R2) in polymer chain of copolymer is the polymer chainlike transition of the two kinds of monomers in the microfield of copolymerization. The relation between the value of Price Q and the localized energy of monomers were also investigated. There were also linear relations in all typical monomers, except acrylonitrile.
