Abstract

In this study, the cyclization reaction products from telechelic polystyrene were precisely analyzed using high performance liquid chromatography (HPLC) techniques, that is, size exclusion chromatography (SEC), liquid chromatography at the critical condition (LCCC) and temperature gradient interaction chromatography (TGIC). It was confirmed that the cyclization reaction products consist of linear and cyclic condensates by LCCC. Furthermore it was found that the linear condensates contain dimers to multimers (∼15), while cyclic counterparts contain dimers, trimers, tetramers and pentamers by SEC and TGIC.
