发帖数: 158 | 7 这问题我自己在网上查了好长时间了，自己也做过一些尝试性的实验，但是结果都不是
很好。所以想在这里请教一下大家，希望有经验的前辈不令赐教。
我现在的目标是合成acrylic acid和acrylamide的copolymer，目标是合成（PAA-co-
PAM）random copolymer而不是block copolymer。聚合的手段是自由基聚合（living
radical polymerization：RAFT）。
我查到的文献和wiki都说，如果直接在一开始就把两种monomer放到一个烧瓶，同时开
始反应，那么产物很有可能是block copolymer。可是我的monomer的propagation
constant差别在一个数量级以内，那么如果一开始就放在一起的话，是不是也会倾向于
生成block copolymer呢？
如果这样做确实会导致生成block copolymer的话，那么我应该怎么做才能生成random
copolymer呢？
另外，检测copolymer是block还是random的方法，除了测Tg，做C-NMR以外，还有什么
比较有效的方法么？
在这里... 阅读全帖 |

发帖数: 158 | 8 是这样的么？我只用过各种living radical polymerization，所以不太敢做普通的自
由基聚合。
普通的自由基聚合不是不容易控制polydispersity和molecular weight么？ |
|
S***k
发帖数: 158 | 9 怎么直接自由基聚合啊？直接加单体和引发剂然后就除氧就好了么？
乳液我知道，但是我们实验室没有相关的设备，超声和强力的搅拌都没有，估计是不能
做乳液聚合了。
说来惭愧，我只做过living radical polymerizaiton，关于不加ATRP、RAFT的
conventional radical polymerization还从来没做过…… |
