RAFT(自由基稳定的单乙基异丁烯酸酯)聚合技术在合成高分子聚合物时得到了广泛应用
本文将讨论非共轭乙烯基单体超支化聚合物的 RAFT 法合成及其性能表征
首先,在文献和样品分析的基础上,选定了合适的单体和 RAFT 引发剂
通过调整反应条件,控制聚合物分子量和分子量分布
然后,使用峰值分离法和核磁共振技术对合成的超支化聚合物进行表征
最后,探讨超支化聚合物的热稳定性、界面活性性和可溶性等性能

The RAFT (reversible addition-fragmentation chain transfer) polymerization technique has been widely used in the synthesis of high molecular weight polymers
In this study, the RAFT method was used to synthesize non-conjugated ethylene-based monomer hyperbranched polymers and characterize their properties
Firstly, suitable monomers and RAFT initiators were selected based on literature and sample analysis
