标 题: 能用RAFT 合成纯block copolymer吗？Macro chain transfer agent 加AIBN和monomer
发信站: BBS 未名空间站 (Tue Jul 12 23:07:51 2011, 美东)
带thio的Macro chain transfer agent （如P4VP-CTA)加AIBN和monomer（如styrene）
能用RAFT合成纯P4VP-co-PS 的block copolymer吗？没做过RAFT。不过从机理来看理论
上应该会有一半是PS 的homopolymer啊！
不知我是否理解有误。请大侠指教！
拜谢！ |

Europe's powerful competi-tion authorities suffered a crushing blow yesterday,
when the European Union's second-highest court ruled they were wrong to block
a merger between the French electrical groups Schneider and Legrand.
The ruling will increase pressure on Mario Monti, competition commissioner, to

发帖数: 95 | 9 请教大家一个问题，
有strongly segregated,amphiphilic block copolymer,完全溶解于某溶剂(polar
solvent, its vapor pressure similar to toluene),做spin-coating制膜，
substrate是hydrophilic silica,总是得到不均匀的表面，应该是dewetting.
现在想得到平整的膜，方便用AFM表征，观察morphology.
一个麻烦的办法是使用neutral surface,就是先在silica上以化学键粘合一层相应的
random copolymer膜，然后再去做block copolymer的coating,有可能有助于避免
dewetting.
请问有什么办法解决？ 欢迎wonderlich老师指教！ |

发帖数: 62 | 15 Below is the problem.
A multi-site agricultural experiment is being planned in which several
varieties of a given crop are going to be allocated to plots within each
site using a randomized complete-block layout. The sites have been chosen
to differ dramatically over the range of the environments in which the crop
is grown. Varietal differences are not expected to homogeneous over the
sites, and the best performing varieties at some locations are not expected
to be the best performing varieti |

发帖数: 19 | 16 The differences in block appear to lie in the different enviromental factors
(e.g. temperature or sunlights). You could group sites in terms of those
factors by cluster analysis.
The grouping may be reasonble if you have too many sites.
It is not clear what is the study purpose. Clearly you cannot make
inference on the overall differences among varieties. However, if you sort
out the important enviromental factors, combing with variety, you may have
a fatorial design problem here. Dependi |

(Scroll down to the bottom, and look at the BLOCK plans.)
It's normally $100, and they only do this offer on select tuesdays
throughout the year. It is a great deal, as the block plans don't expire,
so you don't have to worry about paying monthly fees.
