摘要

以苯乙烯(St)为单体

二硫代萘甲酸异丁腈酯(CPDN)为可逆-加成断裂链转移聚合(RAFT)试剂

合成大分子链转移剂

再加入不同质量的乙烯基三甲氧基硅烷(A171)

得到嵌段比不同的共聚物P(St-

-A171)。通过核磁共振谱仪

H-NMR、凝胶渗透色谱GPC、动态力学分析仪DMA和接触角等方法对P(St-

-A171)结构进行了表征。结果表明:随着

A171

嵌段比从1:0.15增加到1:0.45

P(St-

-A71)数均分子量从10400增加到14000

PDI指数从1.42增加到1.58;聚合物成膜后接触角由78.4°增加到89.6°。通过以上分析得出结论

RAFT合成嵌段共聚物的嵌段比对P(St-

-A171)性能有较大影响。

Abstract

The macromolecules chain transfer agent was synthesized by using styrene (St) as monomer and 2-cyanoprop-2-yl1-dithionaphthalate (CPDN) as RAFT agent. The different block ratio of copolymers P(St-

-A171) were synthesized by dvinyltrimethoxysilane (A171) and macromolecules chain transfer agent. The structure of block copolymer was characterized by

H NMR

gel permeation chromatography GPC

dynamic mechanical analysis (DMA) and other methods. The results showed that the number-average molecular weight of block polymer was increased from 10400 to 14000 and PDI index increased from 1.42 to 1.58 as the block ratio of

A171

increased from 1:0.15 to 1:0.45. The contact angle of block polymer film was increased from 78.4° to 89.6°. Through the analysis above

the

A171

block ratio have great influence on the performance of P (St-

-A171).
