Controlled Swelling of Monolithic Films as a Facile Approach to the Synthesis of UHMWPE Membranes.

The drawback of conducting the swelling process at 106 °C i.e., in region I on the phase diagram, was a quite significant decrease of the film weight due to the thermodynamically allowed process of “washing away” (extraction) of some macromolecules from the film into the o-xylene bath.
