| 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. |
