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 effectivel

## Abstract Polyurethane prepolymers are a complex mixture of oligomers. The proportion of the various species in this mixture determines the handling properties of the prepolymer as well as the physical properties of the final polyurethane. An analytical method has been developed that gives a clea
