The molecular weight distribution of random, unfractionated copolymers of ortho ‐ and para ‐fluorostyrene and ortho ‐ and para ‐chlorostyrene were determined. Good agreement was obtained between average molecular weights determined by absolute methods (light scattering and osmometry) and those determined by high‐performance gel permeation chromatography and a universal calibration procedure. The measurements were carried out in tetrahydrofuran at room temperature by using the following relationships between intrinsic viscosity [η] and weight‐average molecular weight M̄ w ..
