Copolymerization of Norbornene and n-Butyl Methacrylate Catalyzed by Novel Ni(Ⅱ) (benzocyclohexan-ketoarylimino) 2
摘要
Abstract
Vinyl-addition copolymerization of norbornene ( NB ) and polar monomer n-butyl methacrylate ( n-BMA) were carried out via two novel high activity catalysts, Ni (Ⅱ) ( benzocyclohexan-ketoarylimino ) 2 (Ni{C10H8(O)C[2,6-C6H3(CH3)2N]CH3}2, C1) and Ni{C10H8(O)C[2,6-C6H3Cl2N]CH3}2, C2), in combination with tris( pentafluorophenyl)-borance [ B ( C6 F5 ) 3 ] . A possible catalytic deactivation mechanism of polymerization was presented. Influence of monomer feed ratio on catalytic activity, conversion rate and properties of outcomes were investigated. Reactivity ratios of co-monomers were estimated by Kelen-Tüdõs method, they are rn-BMA=0. 02, rNB=16. 28, rNB ·rn-BMA=0. 32 for C1/B(C6F5)3 catalytic system, and rn-BMA=0. 01, rNB=64. 83, rNB·rn-BMA=0. 65 for C2/B(C6F5)3 catalytic system. These indicate the random copolymerization of NB/n-BMA occurs with both C1/B( C6 F5 ) 3 and C2/B( C6 F5 ) 3 .关键词
