Abstract
The formation of interpolymer complexes (IPCs) between hydroxypropylcellulose (HPC) and copolymers of maleic acid with vinyl acetate (MAc-VA), acrylic acid (MAc-AA) and styrene (MAc-S) in aqueous solution has been investigated by turbidimetry, viscometry and fluorescence measurements. The viscosity data indicated a compact structure for the IPCs between HPC and maleic acid copolymers. Besides H-bonding, strong hydrophobic forces materialize between HPC and MAc-S, strengthening this IPC. The strength of the interpolymer interactions was estimated to increase in the order: HPC:MAc-VA < HPC:MAc-AA < HPC:MAc-S. The IPCs of HPC with MAc-VA or MAc-AA were water-soluble at pH values higher than 3, while the IPC between HPC and MAc-S was water-soluble at pH values above 4.5.
