Description

Alkenes, C30-62 .Alpha.-, Polymers With Maleic Anhydride is a high molecular weight polyolefin copolymer derived from long-chain α-olefins and maleic anhydride. This chemical structure provides a unique combination of hydrophobic hydrocarbon chains and reactive anhydride functionalities, making it a versatile intermediate and performance additive. It is primarily utilized in the formulation of industrial lubricants, fuel additives, and specialty polymers where dispersancy, viscosity modification, and surface activity are critical. The product, identified by CAS NO 69669-24-5, is essential for manufacturers seeking to enhance the performance and longevity of their high-end formulations.

Application

• Lubricant & Fuel Additives: Acts as a dispersant and viscosity index improver in engine oils, gear oils, and industrial lubricants to prevent sludge formation and maintain performance across temperature ranges.
• Polymer Modification: Used as a compatibilizer and coupling agent in polymer blends and composites, improving adhesion between non-polar polymers and polar fillers or reinforcements.
• Corrosion Inhibitors: Serves as a key intermediate in the synthesis of ashless succinimide-type corrosion inhibitors for metal surfaces in contact with fuels and oils.
• Detergents & Dispersants: A foundational component in the production of high-performance detergent additives for automotive and marine fuels.
• Adhesives & Sealants: Functions as a tackifier and adhesion promoter in hot-melt and pressure-sensitive adhesive formulations.
• Coatings & Inks: Employed as a rheology modifier and dispersing agent to improve pigment wetting and stability in coating systems.
• Paper Sizing: Utilized in the production of alkyl ketene dimer (AKD) analogs for internal sizing to impart water resistance to paper and board.
