发帖数: 12367 | 4 what's polymer science?
pure polymer science is dead,
because once it was established before 1980,
it has to find ways out.
now, polymer people have to do further based on the initial concept of LONG
CHAIN with other fields such as physics, surface science, materials science,
chemistry, simulations, bio, information, EE, ME, ChE...

发帖数: 40 | 5 kind of agree, but i am not expert at the chain theory. you mean polymer
people care more about application instead of fundamentals, i also agree, coz
thats what polymer is used for.
then, what do u think is the major advance in recent 10 years?

几个方向吧，瞎说说，都是一大块一大块的：
（1）Sharpless在宣传他的click chemistry，高分子合成设计仍然是重要方向；
（2）复杂系统的高分子动力学，包括生物体系；
（3）功能性先进材料---〉更优化，以全面代替传统材料。
//I am not saying polymer people should not care about fundamentals,
just instead. otherwise, nothing to deeper those directions.

soft electronic device made by organic or polymer will replace low end silicon
devices in less than 10 years. hehe. means hundred thousand job positions and
hundred thousand layoff.
just be aware of this.

发帖数: 238 | 9 Grubbs definitely is very promising, but he is doing almost pure chemistry, we
may count him in as one like Zigler or Natta. This is my feeling, I'm not sure
about this.
The other people we usually count as polymer scientist, Flory, de Gennes,
A.J. Heeger all bring in new concepts to chemistry and physics, sometimes even
introduce new fields and ideas. Maybe Grubbs can do the same.

发帖数: 3525 | 13 W Kaminsky, H H Britzinger and J A Ewen will possibly be awarded the Prize for
their contribution to the homogeneous catalysis, stereoselectivity, and
mechanism in olefin polymerization. Homogeneous catalysis has made it possible
to study the polymer chain growth and stereo-control mechanism, which was
unclear based upon hetereogeneous Z-N catalysts.
Kaminsky's contribution is in that he prepared MAO, the cocatalyst for olefin
polymerization, which dramatically increases the catalytic activity t

发帖数: 199 | 14 Single site catalysis is definitely important.
For Ewen, he also found Cs type catalyst which can get syndiotactic pp.
He also got president medal last year,I think
he should have more chance than TJ Marks
for
possible
olefin
million
polyolefins.

发帖数: 1648 | 15 right, I recently read an article about ROMP's history when I was reviewing my
polymer chemistry. It's pretty interesting, and now I have some new thoughts
about the role of Grubbs. Furthermore,unlike MAO catalysts, ROMP couldn't been
widely used in industrial applications. After reading this article, I strongly
agree with agostic, Kaminsky deserve Nobel better than Grubbs.
