Interpreting the copolymerization of styrene with maleic anhydride and with methyl methacrylate in terms of the bootstrap model

The bootstrap model was proposed by Harwood to explain copolymer sequence distribution which is dependent only on copolymer compn. in solvents which cause changes in the apparent reactivity ratios for a no. of pairs of monomers. An explicit formulation of the equations describing copolymer compn. and sequence distribution in terms of the bootstrap model was presented for both the simple Mayo-Lewis model and the penultimate unit model. Inspection of these equations revealed the necessary and sufficient conditions for sequence distribution to be a function only of copolymer compn. The results of copolymns. of styrene with Me methacrylate and with maleic anhydride under various conditions are interpreted in terms of the bootstrap model
