Is there commercial source of all acrylics TPE? Thanks! |

It's the same logic here. Every polymer has its unique properties.

also make deal of "acrylic-styrenic hybrid system" or sth else, hehe

发帖数: 2145 | 9 hehe,我试图促使相关人士“有压力的思考”， 过后你会感到如释重负的愉悦，呵呵
其实我也有点迷糊，正在做一个all acrylic surfactant，不知道咋吹

只有pilot plant级别。呵呵，我手上有样品。 |

发帖数: 1745 | 12 是可乐丽的，不过有可能你要不到free sample。他们产量很小。还没推广，官方主页
上都没有介绍。
我是当时他们有人在德国拜罗伊特的一个会议上做报告的时候接触到的。 |

发帖数: 1652 | 13 哦，谢谢你的信息。
既然谈到ATRP，就顺便来点牢骚。按理，一个好的活性聚合，应该可以做到低分散，高
分子量，以及干净的嵌段聚合。ATRP这些年，引无数英雄折腰，还是没捣出过个像样的
TPE（也许我错了？）。可见大家多浮躁。

发帖数: 1745 | 14 不跑题，还是说这个高分子，下面是我了解到的的一些信息。
using (complex) initiator which consists of a bulky aluminum compound,
utilized in the presence of a Lewis base (polyethers, polyamine, etc.), in
Toluene from -30°C- -0°C
sec-BuLi, tert-BuLi, --- initiator.
isobutylbis(2,6-tert-butyl-4-methylphenoxy)aluminium ---- co-initiator.
2-dimethoxyethane (DME) ----- Lewis base.
PMMA含量分别为32％，或者是50％， 最终产物透明度可达91% |
