Synthesis of poly(styrene-b-tetrahydrofuran (THF)-b-styrene) triblock copolymers was performed by transformation from living cationic into living radical polymerization, using 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl (4-hydroxy-TEMPO) as a transforming agent. Sodium 4-oxy-TEMPO, derived from 4
## Abstract The polymerization of styrene was studied by using a bifunctional initiator, 1,4βbis(1βchloroethyl)benzene (1). It was demonstrated that living polymerization can be achieved in the styrene/1/SnCl~4~ system in chloroform at β15Β°C in the presence of 2,6βdiβ__tert__βbutylpyridine. The num
