Abstract Syndiotactic poly(2-methylheptyl methacrylate) which was gamma-irradiated at room temperature to a dose of 1600 kGy was investigated by NMR spectroscopy. The H-1 and C-13 resonances for the macromolecular chain were assigned by using the 2D and the DEFT (distortionless enhancement by polarization transfer) technique. The spin-echo modified 2D NMR pulse sequence was used to investigate the small molecules and new structures which were formed during gamma-irradiation. The radiation mechanisms for cleavage of the side chain from the main chain and formation of double bonds from both the main chain and the side chain have been formulated based upon the NMR analysis.
