Taking account of the influences of both side groups and hetero‐atoms in backbone, the mean‐square radius of gyration of poly[oxy(1‐alkylethylenes)] has been derived by the method of the rotational isomeric state approximation and matrix algebra. Numerical calculation with the parameters available in literature indicated that the dependence of 〈 S 2 〉 on the molecular weight can be expressed as the general formula, 〈 S 2 〉 = aM b with b = 1 ± 0.02, for poly(oxypropylene), poly[oxy(1‐ethylethylene)] and poly[oxy(1‐tert‐butylethylene)]. © 1997 John Wiley & Sons, Ltd.
