Preparation of Cyclic PolyAcrylates for Improved Strength and Durability

Abstract

In this work a new class of cyclic chain transfer agents based on current RAFT agents and TARO-based RAFT agents are synthesized to prepare cyclic polymers using photoRAFT or PET-RAFT. Cyclic CTAs synthesized in this work were evaluated with a series of different monomers, and under various conditions, but no significant polymer formation was observed under any set of experimental conditions. Computational analysis determined that the geometry of the cyclic CTAs prepared in this study are not idea for C-S bond homolysis, and therefore are not expected to act as an iniferter in a photoRAFT process.
