ABSTRACT OF THE DISCLOSURE Improved active agent systems with novel carriers as membrane, release, and coating polymers for said active agents; the polymers are water absorptive polyurethane polymers prepared from resins having a low ratio of carbon to oxygen to nitrogen or having ionic, quarternary ammonium or salt groups in the resin backbone and a low amount of isocyanate; the water absorbtivity of the polyurethane polymers is above 10%, preferably above 20%, and these polymers may range to completely gel-like, high water absorbtive polymers; these active agent polymers are useful as in medicinal, insecticidal, pesticidal, algaecidal, etc. applications; as well as zero release agents, body implants and coatings requiring hydro- philic properties; other use for the active agent systems are in sensing membranes or coatings or ion transport recognition devices such as a gaseous or liquid media; as a hydrogel providing a leachable matrix wherein the leaching agent may be body fluids, e. g., animals or human, e. g., productive livestock and domestic animals and/or pets, or animals used in medicinal or veterinary research, e. g., monkeys, mice, dogs, hamsters, rabbits, guinea pigs, cats, etc.
