摘要

The presumable change of monomer feed composition in the vicinity of the propagating macroradical due to formation of a polymer microphase specifically affects is the composition and microstructure of the obtained copolymer. The quantitative aspects of this so-called boot-trap effect are compared in the cases of propagation obeying terminal, penultimate, or complex addition mechanism. An attempt is made to demonstrate which propagation mechanisms lead to an unambiguous relation between copolymer composition and microstructure, New methods are proposed for the determination of the intrinsic parameters of the above mechanisms including an indirect though absolute method for the determination of the monomer distribution between the solvent and the polymer microphases. The results could help to relate more reliably the copolymerizations studied experimentally to a certain theoretical model. A set of quantitative criteria is proposed to this aim. [References: 16]
