Abstract

The ^13^C methylene carbon absorptions of poly(methyl methacrylate) with a random structure were assigned in terms of tetrad sequences using the 2D COSY (^1^Hโ€^13^C) NMR spectrum and by comparison with the absorptions of isotacticโ€rich and syndiotacticโ€rich poly(methyl methacrylate)s. The rrr, rmr and mmr tetrads were further assigned in terms of hexad sequences.
