Radical copolymerization of functional N-substituted maleimides with N-vinyl-2-pyrrolidone
Two functional N-substituted maleimide monomers, namely N-(4-carboxyphenyl)maleimide (CPMI) and N-(4-formylphenoxy-4?- carbonylphenyl) maleimide (FCPMI), were copolymerized with N Vinyl-2-pyrrolidone (NVP) at 90 C in the presence of 2,2?-azobisisobutyronitrile as initiator in dimethylformamide. The monomers reactivity ratios were calculated by extended Kelen-Tu?do?s and Mao-Huglin methods. The average reactivity ratios and Alfrey-Price Q and e Values were found to be r1 = 0.028, r2 = 0.347, Q1 = 0.035, e1 = 1.013 for CPMI/NVP system and r1 = 0.044, r2 = 0.060, Q1 = 0.145, e1 = 1.297 for the FCPMI/NVP system. The distribution of monomer sequences along the copolymer chain was calculated using a statistical method based on the obtained reactivity ratios. The thermal properties of the resulting copolymers were also investigated. These copolymers exhibit fairly high thermal stability with decomposition temperatures above 230 C. The effect of the N-substituents on the radical copolymerization of the above functional maleimides with NVP is discussed.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C11H7NO4, you can also check out more blogs about17057-04-4
