Description

Acetic Acid Ethenyl Ester, Polymer With .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,2-Ethanediyl), Graft is a specialized graft copolymer that combines the properties of polyvinyl acetate and polyethylene glycol (PEG) segments. This unique structure provides excellent film-forming, adhesive, and surfactant characteristics, making it a valuable functional polymer. It is primarily used in advanced industrial applications where controlled release, enhanced compatibility, or specific rheological modification is required. Key sectors that utilize this polymer include pharmaceutical formulation, specialty coatings, and advanced material science.

Application

• Pharmaceutical Excipient: Used as a binder, film-coating agent, or matrix former in controlled-release tablet and capsule formulations.
• Specialty Adhesives: Serves as a key component in pressure-sensitive adhesives (PSAs) and remoistenable adhesives due to its tackifying and film-forming properties.
• Coatings & Inks: Acts as a polymeric additive in industrial coatings, printing inks, and overprint varnishes to improve gloss, flexibility, and substrate adhesion.
• Personal Care Products: Functions as a film former and stabilizer in hair styling gels, mousses, and skin care formulations.
• Textile & Fiber Treatment: Employed as a sizing agent or finishing chemical to modify fabric hand, durability, and moisture management.
• Paper Coating: Enhances the strength, printability, and surface smoothness of specialty papers and paperboard.
• Polymer Modification: Used as a compatibilizer or impact modifier in polymer blends and composites to enhance performance characteristics.
