Summary:The article analyzes a study on elevated temperature polymerization techniques with o-F substitution in Ti complexes. Living polymerization is an essential tool for the synthesis of polymers and requires the absence of chain termination and irreversible transfer. Restrictions on catalyst activity and molecular weights in polymerization at low temperatures were sought to be minimized in the study. Comparison of results by varying reaction conditions are also discussed.
