Description

Poly(Ethylene-Alt-Maleic Anhydride) is an alternating copolymer of ethylene and maleic anhydride, known for its reactive anhydride functionality and versatile polymer backbone. This structure is critical for its role as a key intermediate and performance additive, enabling covalent bonding and property modification in various formulations. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to enhance material adhesion, crosslinking density, and surface functionality.

Application

• Adhesive & Sealant Formulations: Acts as a reactive tackifier and crosslinking agent to improve bond strength and thermal resistance.
• Surface Coatings: Used as a curing agent and adhesion promoter in epoxy, polyester, and alkyd resin systems for industrial and protective coatings.
• Polymer Modification: Serves as a compatibilizer and grafting agent to improve the properties of polymer blends and composites.
• Paper Sizing & Treatment: Enhances the wet strength, printability, and barrier properties of paper and paperboard.
• Textile Finishing: Utilized to impart durable press properties, soil release, and improved dyeability to fabrics.
• Scale Inhibitor & Dispersant: Functions in water treatment formulations to control mineral scale and disperse particulates.
