发布时间:2018-04-13 浏览次数:

Dongmei Chen, a research professor at Changchun Institute of Applied Chemistry Chinese Academy of Sciences, was invited to deliver a talk on the new method of polymer sequence controlled polymerization on Jan. 12, 2018. It was hosted by Professor Daohong Zhang.

She introduced the synthesis and application of polymer sequence controlled polymerization. Through changing catalyst center metal and conpolymerization of butadiene and styrene, a series of block, wedge, gradient and random distributed polymers were synthesized. It was found that the diameter of the metal ions of organo-metallic catalysts had an effect on polymerization.Sequence controlled conpolymers of polar and nonpolar polystyrene were obtained through design of catalyst arm, various Monomer substituting positions and active center coordination models. The relationship between catalysts, polymerization, morphology structure and properties was discovered through the difference in physical and mechanic properties of various conpolymers. The talk was warmly welcomed by audience, resulting in active discussion. It helped the researchers to learn better about polymer sequence controlled polymerization.

Dongmei Chen, a research professor at Changchun Institute of Applied Chemistry Chinese Academy of Sciences, was admitted to The Hundred People Plan of the Chinese Academy of Sciences in 2005, won Special Allowance of the State Council in 2013, was elected as Zhu-Li-Yuehua Excellent Teacher in 2014, and was honored as CAS-SABIC Excellent Scholar in 2015. Her research interests are design of metal catalysts and polymer sequence controlled polymerization. She published over 160 research papers at J. Am. Chem. Soc., Angew. Chem. Int. Ed., Chem. Eur. J., Chem. CommMacromolecules, Polym. Chem. Organometallics. and so on. Her publications were cited for more than 1800 times. She owned 18 patents of invention in China, 14 PCT, 13 licensed patents, one USA patent and one European patent.
