Polymer 2-Polymer 3 interactions in water 1/polymer 2/polymer 3 ternary systems

Abstract

The polymer 2-polymer 3 interactions Δb23, for water-poly(ethylene glycol) (PEG) poly(vinyl alcohol) (PVA), water-poly(N-vinylpyrrolidone) (PVP) PVA, water-dextran (Dex) PVA, water pullulan (Pul) PVA, water-PVP PEG, water-Dex PEG. water Pul PEG, water-PVP Dex, water-Pul-PVP system were studied. For only the water-Dex-PVA system, Δb23 is positive, but for the other systems negative. This indicates that most polymer pairs have repulsive interactions and are incompatible in water.
