✦ Synopsis

Formation of branched polymers often occurs during the preparation of linear polymers. Moreover, if an attempt is made to prepare for comparison purposes some branched polymers (comb or star shaped), generally mixtures with the corresponding linear polymers are obtained.

In the course of the present work we considered, for comparison with the linear polymer, polycaprolactam artificially branched with a star shape. Such a shape was selected as it strongly indicated the differences from the linear product.

The aim of the present paper was the comparison of fractionation behaviours of linear and branched polymers.

Fractionations have been carried out by continuous extraction from a coacervate phase.
