Abstract Fractions of commercial polyvinylbutyral “Movital” were investigated by the “off‐line” combination of gel permeation chromatography and viscometry. Parameters of the Mark–Houwink equation were determined for polyvinylbutyral in tetrahydrofuran at 25°C. Real values of the molecular parameters were obtained by the evaluation of chromatographic data using the principle of universal calibration.
