嵌段共聚物作为合成材料,例如热塑弹性体和工程塑料,具有较大的应用价值和理论意义。关于嵌段共聚物的重均分子量,前人已有定义,但对式中的Rempp-Benoit项尚缺乏进一步的研究。因此,还不能对嵌段共聚物的重均分子量作有效的数值计算。此外,重要的Callot不等式亦不曾在理论上得到应有的证明。阴离子型活性共聚合反应是合成嵌段共聚 Block copolymers as synthetic materials, such as thermoplastic elastomers and engineering plastics, have great application value and theoretical significance. The weight average molecular weight of the block copolymer has been defined as above, but there is no further study on the Rempp-Benoit term in the formula. Therefore, the weight average molecular weight of the block copolymer can not yet be effectively calculated. In addition, the important Callot inequality has not been properly proved in theory. Anionic reactive copolymerization is a synthetic block copolymerization
