## 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^Hβ^13^C) NMR spectrum and by comparison with the absorptions of isotacticβrich and syndiotacticβrich poly(methyl methacrylate)s. T
## Abstract The orientational distribution in drawn amorphous poly(methyl methacrylate) extended to the ratio Ξ» = 3 was measured with oneβ and twoβdimensional carbonβ13 NMR spectroscopy. In the analysis, signals from the carboxyl carbons were used as a probe of the orientational distribution. The a
