Molecular mechanics calculations are reported on barriers to rotation in model compounds for poly (propyl methacrylate). The results present strong evidence that the so-called 7-maximum in the mechanical loss measurements must be attributed to hindered rotation around the OCH2-CH2 bond of the propyl group
