The solution properties of poly‐o‐chlorostyrene

Abstract The solution properties of poly‐o‐chlorostyrene in toluene were measured by means of light‐scattering and viscosity method, and the results were compared with those obtained from other polystyrene derivatives. The dependence of the intrinsic viscosity, the second virial coefficient and the end‐to‐end distance of the polymer chain on the molecular weight is follows: These relationships do not differ substantially from those of other polystyrene derivatives. The unperturbed dimension of poly‐o‐chlorostyrene was calculated. Results showed that the polymer chain of poly‐o‐chlorostyrene at the theta state, { 2>o/ 2>f}1/2 = 2.42, was more extended than that of poly‐p‐chlorostyrene, { 2>o/ 2>f}1/2 = 2.15 to 2.30.
