Abstract

The formula for calculating the mean-square radius of gyration of polyethylene was deduced by matrix method taking into account the effect of H atoms. The derived formula was simplified to the Flory's formula if the mass of H atoms was ignored. The relation between and mol. wt. (M) could be expressed as 1/2 = 0.44M1/2, which agreed with the experimental data in q solvent, i.e., 1/2 = 0.45 ?0.08M1/2.
