What is it about?
PMDL and PVPh are miscible based on H-bond interactions. In the system PMDL+PVPh+THF, the low-MW polymer pair forms soluble blend. The high-MW pair undergoes fractionation into the high-MW fraction forming insoluble inter-polymer complex due to associative phase separation and the low-MW fraction forming soluble blend. Average molar ratio of PMDL/PVPh in the complex is 1:2.

Why is it important?
To the best of our knowledge, this is the first time that a system containing two strongly interacting polymers has been described based on associative phase separation resulting in formation of inter-polymer complex and soluble blend. The process has been named "fractional complexation".
Perspectives
The topic of polymer miscibility is important from both the scientific and technological point of view.
