Abstract
Sequence distributions of acrylate–methacrylate copolymers were evaluated with Yamaguchi–Yokoyama’s pyrogram. The diad concentration ratio of P2(acrylate–acrylate) to P2(acrylate–methacrylate) was empirically estimated by the peak area ratio of related acrylate monomer to dimer. Sequence distributions of diad in the ethyl acrylate (EA)–butyl methacrylate (BMA) copolymer, synthesized under different conditions, were comparatively evaluated. Their sequence distributions were also possible to evaluate by the peak area ratio of EA–EA dimer to EA–BMA dimer on their pyrogram. The results from the former method were in good agreement with those from the latter method. Furthermore, the method principally the same as the former was applied to evaluate the diad concentration ratios in EA–butyl acrylate (BA)–BMA terpolymers.
