MEASUREMENT OF UNPERTUBED DIMENSION 0F POLYMER*

TIAN Bingshou

Received Date: 23 May 1985

The unperturbed dimension of polymer is measured by a gel permeation chromatography (GPC)coupling with viscometer. The intrinsic viscosities of the fractions are measured with an automaticviscometer, and the molecular weight of the fractions are calculated based on the universal calibration.Using a theoretical expression with linearized Mark-Houwink's equation an unperturbed dimensionis obtained by extrapolating to the unperturbed state. The results agree with the values measured by conventional method comparisons with various theoretical expressions are made.
