环形聚苯乙烯是两端带活性基团的线形聚苯乙烯径环化反应,使两端以化学键相连而合成。线形聚合物的玻璃化温度(T_g)已得到广泛深入的研究,但环形聚合物的玻璃化温度却
Cyclic polystyrene is a linear polystyrene radial cyclization reaction with reactive groups at both ends, which are synthesized by chemical bonding at both ends. The linear polymer glass transition temperature (T_g) has been extensively studied, but the ring polymer glass transition temperature
