The products with higher conductivity are mainly 1, 4-connected head-to-tailchain structure, both benzenoid and quinoid units exist in the polymer chain.
具有较高电导的产物的链结构主要是1,4 -连接的头尾结构,链上同时存在苯式及醌式两种结构单元。

Due to the existence of the surface, the curves expressing the chain size versus temperature for the tailchain were slightly lower than those for the free chain.
由于刚性壁的影响,使得有限链长的高分子尾形链与自由链相比,其表示链尺寸温度关系的曲线要稍低。

It shows that the content of head-to-tailchain of the polymer are related to its polymerization temperature, but are not related with the kind of initiators used.
