โœฆ Synopsis

A recycle gel permeation chromatograph with polystyrene gel as the column packing was devised for the separation and identification of oligomers and polymer additives. The chromatograph was equipped with a differential refractometer and an ultraviolet detector.

Oligomers can be separated effectively by means of the recycle technique. Various additives in commercial resins can be separated without using the recycle technique, and the individual components can be identified by comparison of the distribution coefficient and sensitivity of the two detectors by the use of known compounds.
