## Abstract The calculations of the meanβsquare radius of gyration for more than thirty sorts of polymer chains are reviewed on the basis of a unified approach. A general expression of the meanβsquare radius of gyration was developed for polymer chains with side groups and/or heteroatoms. It consis

β¦ Synopsis
The mean-square radius of gyration of polyethylene chains, considering the effect of hydrogen atoms, is investigated by using Monte Carlo simulation and the rotational isomeric state model. It is found that the mean-square radius of gyration of the chains may be expressed as
This simulation can provide a method to investigate the mean-square radius of gyration of polymer chains.

## Abstract The meanβsquare radius of gyration for polysiloxanes has been derived according to the exact definition. Taking account of the examples of symmetrically substituted poly(dimethylsiloxane) and unsymmetrically substituted poly(methylphenylsiloxane), we find that the dependence of γ__S__^2
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 o
The mean-square radii of gyration of cisand trans-I ,4-polybutadiene and corresponding I ,4-polyisoprene were derived using Abe's and Flory's rotational isomeric scheme. Calculations performed using available experimental data showed that the dependence of the mean-square radius of gyration on the m
## Abstract Equations for the mean square radius of gyration and the hydrodynamic radius for jointed stars (dumbbells) and Hβcombs are derived, based on random flight statistics for each subchain. Comparision with literature data on computer simulations and experimental data for Hβcombs show good a
