Drying substances, preparation and use thereof

Abstract

There is provided herein a dryer polymer substance including a hetero-phase polymer composition including two or more polymers wherein at least one of the two or more polymers include sulfonic groups, wherein the substance is adapted to pervaporate a fluid. The fluid may include water, water vapor or both. There is also provided herein a process for the preparation of a dryer polymer substance adapted to pervaporate a fluid (such as water, water vapor or both) the process includes mixing two or more polymers, wherein at least one of the two or more polymers may include groups which are adapted to be sulfonated, to produce a hetero-phase polymer composition and processing the polymer blend into a desired form.
