## Abstract Syndiotactic poly(2‐methylheptyl methacrylate) which was γ‐irradiated at room temperature to a dose of 1600 kGy was investigated by NMR spectroscopy. The ^1^H and ^13^C resonances for the macromolecular chain were assigned by using the 2D and the DEPT (distortionless enhancement by pola
Ultrasonic absorption measurements were made at 3.14 MHz on poly( methyl methacrylate) as a function of temperature and after various doses of y-irradiation. The measurements showed a relaxation phenomenon. The activation energy of the various doses was determined and the smallest doses that affecte
