Kinetic Study of Ion-Sensitized Termination of Radical Polymerisation

摘要

Rates of linear termination of polymerisation by metal perchlorates (Fe, V, U) were measured at different temperatures and Arrhenius parameters determined. No correlation between rate constant and any thermodynamic property was found. Rate constants for termination by ferric chloride and sulphate were much greater than that for termination by ferric perchlorate. Uranyl perchlorate and ferric chloride were found to initiate polymerisation by a thermal mechanism. (Author)
