Moisture barrier resins

Abstract

Moisture barrier resins comprising a film-forming, cross-linkable, partially hydrolyzed polymer and a cross-linking agent provide improved impermeability to moisture and extended release capabilities for various particles, substances and other core materials that are encapsulated with compositions which contain these resins.
