摘    要:根据成环反应和扩链反应竞争的具体条件,在Ruggli高稀释理论的指导下,设计出了一种符合无限稀释和守成现场成环的高度稀释装置,确定了三种合成大环高分子的技术路线,并在接近临界浓度的条件下达到定量的成环转化效果。

关 键 词:高稀释理论  竞争反应  临界浓度  大环高分子  合成  成环反应  缩聚反应  尼龙-6

Abstract:According to the Ruggli high dilution theory and condition of concurrent reaction between the cyclization and chain extension we have designed a high dilution unit used for the objective of infinitely dilution and therefor the first to realize the cyclization of in situ technique, decided three different synthesis lines (multi-step-cycle cyclization method, continuos cyclization in situ method and high dilution cyclization in situ method) of ring-shaped polymers, and at the almost nearing of critical concentration Ccri approach to the effect of quantitative cyclization.
Keywords:high dilution theory  concurrent reaction  critical concentration  high dilution unit
