Dielectric constants have been determined for poly(oxytetramethylene) and poly(oxydecamethylene) chains in the thermodynamically good solvent benzene. The data for the former polymer indicate that the dipole moment ratio 〈μ2〉/(Nm2), is independent of the chain length as has been predicted for chains of such structural features. The value of this ratio for α‐hydro‐ω‐hydroxypoly(oxydecamethylene) chains is in the same range as that obtained for poly(oxyethylene), poly(oxytetramethylene) and poly(oxyhexamethylene) and is in fair agreement with that predicted by the isomeric state theory.
