Interpretation of Solvent Effects on Styrene/Maleic Anhydride Copolymer Sequence Distribution and Microstructure in Terms of the Bootstrap Effect

Abstract

Solvent effects on the copolymn. of styrene and maleic anhydride are interpreted in terms of Harwood's bootstrap effect. Earlier observations that this comonomer pair behaves according to the bootstrap effect are confirmed. Furthermore, solvent effects on stereochem. configuration can be interpreted in terms of the bootstrap effect as well. The observation that the cis/trans (Z/E) ratio (Zusammen/Entgegen) of the anhydride units vs. copolymer compn. is independent of solvent is attributed to monomer partitioning between the bulk of the soln. and the locus of polymn
