In this paper, a method is described that makes easier application of Chang
's method for the determination of molecular weight of copolymers by GPC. D
eterminations of molecular weight of EP-copolymers have been performed with
this method. The values of the resultant weight- and number-average molecu
lar weight are rather close to the experimental data, and the values of int
rinsic viscosity [eta](c) are close to the values measured with Ubbelodhe v
iscometers [eta](d).
