✦ Synopsis

Abstract

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~.

## Abstract The weight‐average molecular weights (M̄~w~) of nominally random, unfractionated copolymers of __ortho__‐ and __para__‐fluorostyrene and __ortho__‐ and __para__‐chlorostyrene were determined by light scattering measurements in tetrahydro‐furan, toluene, carbon tetrachloride and chlorofo
