Giulio Natta was born at Imperia on February 26, 1903. He graduated in
Chemical Engineering at the Polytechnic of Milan in 1924 and passed the
examinations entitling him to teach there in 1927. In 1933 he was established
on the staff of Pavia University as a full professor and at the same time was
appointed director of the Institute of General Chemistry at that University,
where he stayed till 1935, that is until he was appointed full professor in

The NFL and its players continue to try to find a compromise regarding
protests during the national anthem and how best to approach social justice
reform, but a recent comment from Houston Texans owner Bob McNair is
unlikely to improve relations.
McNair said "we can't have the inmates running the prison" in reference to
NFL players protests during an owners session at the recent league meeting,

发帖数: 12367 | 23 Living anionic polymerization was found in 1956 by Szwac.
Ziegler-Natta found catalysts around mid 50 too.
(1)The advantage of ATRP is very clear.
it conbines the advantages of free radical polymerization and living (or
controllable) polymerization together.
(2)People benefit from ATRP because it offers an easy way to synthesize
polymers with designed structure.
(3)Industrialization is very important, but it is not impossible. The key part
is to solve the catalyst problem.

发帖数: 238 | 24 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. |

佐证：
web of science, search using "POLYMERIZATION" from 1900-2007:
除掉两篇生物的actin polymerizaiton，前十名分别为以下。
其中综述文章6篇，分别是Grubbs的两篇，马先生的1篇，
zigler-natta一篇，纳米复合材料两篇。
原创性research paper仅4篇，被引用均超过1000次。
其中Grubbs两篇，王锦山和马先生的一篇，Sawamoto一篇。
Grubbs已经得过了，
如果以后高分子化学有希望再次得到诺贝尔奖的话，
马先生和日本的Sawamoto的ATRP将是最有力的候选，
王锦山因为离开学术界，能不能得到，就看委员会是怎么看了。。。。
