摘要：

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 gamma-maximum in the mechanical loss measurements must be attributed to hindered rotation around the OCH2-CH2 bond of the propyl group.
