Conditions required for the molecular weight and molecular weight distribution determination of fluoropolyoxyalkylenes by gel permeation chromatography are reported and discussed. Experimental work was carried out with three series of narrow fractions of oligomers having the same perfluorinated copolymeric body and three different types of chain ends. The same calibration curve describes very well the behavior of the three series of samples, so that a “size‐exclusion” mechanism of the molecular separation can be postulated practically. © 1994 John Wiley & Sons, Inc.
