Not 100% on this so someone can correct me if they disagree. Since it's a long and flexible polymer chain, I would suspect it might prefer to interact with itself rather than the solvent. It can coil around so that the non-polar, hydrocarbon backbone interacts with itself rather than polar H2O molecules, and its hydroxyl groups can hydrogen bond with each other. This is only an educated guess though.
