SDS of cas: 91-00-9. Recently I am researching about RING-OPENING METATHESIS; PALLADIUM COMPLEXES; POLYMERIZATION; COPOLYMERIZATION; ETHYLENE; 1-ALKENE, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [51963015, 51463014, 21674045]. Published in ELSEVIER SCIENCE SA in LAUSANNE ,Authors: He, XH; Duan, YP; Guo, Y; Wang, K; Wu, B; Wen, YF; Zou, JH; Zhu, CY; Huang, SM; Chen, DF. The CAS is 91-00-9. Through research, I have a further understanding and discovery of Diphenylmethanamine
Three novel hexacoordinated nickel catalysts containing salicylaldbenzhydrylimine ligand and tetrahydrofuran heterocycle, Ni{(THF) (3-R-1) (5-R-2)C6H2(O)CHNCH(C6H5)(2)}(2), (R-1 = Br, R-2 = H, Ni1; R-1 = Br, R-2 = Br, Ni2; R-1 = Cl, R-2 = Cl, Ni3.), were synthesized and their molecular structures were confirmed by X-ray crystallography. Ni1-Ni3 catalysts exhibited high activities (0.53-2.11 x 10(6) g(polymer)/mol(Ni).h) toward norbornene homopolymerization and high activity (0.29-2.62 x 10(5) g(polymer)/mol(Ni).h) to copolymerization of norbornene and 1-hexene. When the 1-hexene feed ratio was changed from 10 to 70%, the 1-hexene content in the obtained copolymers could be controlled to 8.23-26.58%. The Ni3 with R-1 and R-2 were both electron withdrawing groups (-Cl) on the aromatic ring of salicylaldehyde, showed the highest activity as well as the highest 1-hexene insert ratios. At the same time, only a small amount of B(C6F5)(3) cocatalyst (5 x 10(-5) mol) need to be consumed in the copolymerization process. In addition, the obtained copolymers had a high thermal decomposition temperature (T-d > 386 degrees C) and a low glass transition temperature (T-g = 208.67-237.42 degrees C), which showed that the processability of these polymers was improved while the high thermal decomposition temperature was kept. The copolymers also exhibited good solubility in general organic solvents and high optical transparency in the visible region. (C) 2020 Elsevier B.V. All rights reserved.
