摘要

采用可逆加成断裂链转移(RAFT)聚合方法合成了一系列含氟嵌段共聚物(bcp)，其中一个嵌段由无规乙烯基共聚物组成。尽管无序共聚物嵌段中两种单体的性质差异很大，但在160℃退火24 h后，SAXS观察到高度有序的层状结构，分辨率低于10 nm。每个微畴由两个均匀分布的单体组成，温度低至24℃。

Synthesis of Ordered Fluorinated BCPs with One Block Composed of Random Copolymer

A series of fluorinated block copolymers (BCPs), with one block composed of random vinyl copolymers were synthesized by reversible addition fragmentation chain-transfer (RAFT) polymerization. Despite of the hugely different properties of the two monomers in the random copolymer block, highly ordered lamellar structure with sub-10 nm resolution was observed by SAXS after 160 ºC annealing for 24 h. Each micro-domain consisted of two uniformly distributed monomers, with a low T g down to 24 o C.
