Dielectric and infra-red experimental evidence on methacrylate polymers is reviewed. These results are discussed in terms of a model proposed for dielectric relaxation of polar polymer in a matrix of arbitrary compliance. As the side-chain length increases, the symmetry of the orienting segment decreases, causing the strain energy to offset any reduction in the free energy due to interactions of the dipoles,/3, with the applied electric field, E.
