✦ Synopsis

The mean-square radius of gyration of polymer chains with side-groups was formulated using the method of matrix algebra with the rotational isomeric state approximation. If the effect of the side-groups is neglected, the expression reduces to that reported by Flory. The molecular weight dependence of the root-mean-square radius of gyration for isotactic polypropylene was obtained as

in fair agreement with experimental data from small-angle neutron scattering, reported by Ballard et al.

## Abstract The effect of the location of the halogen atom on the distribution of activation energies associated with the subglass relaxation of poly(__o__‐chlorophenyl acrylate) (POCPA) and poly(__m__‐chlorophenyl acrylate) (PMCPA) is studied. Poly(__p‐__chlorophenyl acrylate) (PPCPA) was also inv
