On April 12, 2007, Chung, Young-Keun; Jung, Il-Gu; Chun, Sung-Ho; Park, Young-Whan; Yoon, Sung-Cheol; Lim, Taesun; Lee, Jungmin; Choi, Dai-Seung published a patent.Recommanded Product: 934008-48-7 The title of the patent was Metal complex catalysts for polymerizing cyclic olefins. And the patent contained the following:
Cyclic olefin-based monomers are polymerized using a metal catalyst complex represented by: [M(L1)x(L’2)y(L3)z]a[Ani]b wherein M is a Group X metal; [M(L1)x (L’2)y(L3)z] is a cationic precatalyst; L1 is an anionic hydrocarbyl-containing ligand; L’2 is a neutral ligand; L3 is an N-heterocyclic carbene ligand; [Ani] is an anion capable of weakly coordinating with the metal M; x is 1 or 2; y is 0 to 4; z is 1 or 2; 2鈮+y+z鈮?; a and b are each 1 to 10. The metal catalyst complex has an N-heterocyclic carbene ligand, and thus, is excellent in thermal stability and reactivity. The experimental process involved the reaction of 1H-Imidazolium, 1,3-bis[4-iodo-2,6-bis(1-methylethyl)phenyl]-, chloride (1:1)(cas: 934008-48-7).Recommanded Product: 934008-48-7
