Selective Molecular Absorption from Low Molecular Weight Mixed Solution to a Polymer P4MP1 Film

Abstract

Recently isotactic poly(4methyl1pentene) (P4MP1) has been found to selectively absorb long-chain alkanes from alkane mixed systems. In this article, we introduce the idea of this study from the pressure-temperature phase diagram. We also show that such selective absorption characteristics can be explained from a simple model, namely Asakura-Oosawa theory, and the relationship with molecular recognition is explained.
