Description

cis-1,3-Butadiene Polymer, Maleinized is a chemically modified polymer where maleic anhydride or maleic acid is grafted onto a polybutadiene backbone, introducing reactive carboxylic acid groups. This functionalization is critical for enhancing adhesion, compatibility, and reactivity, making it a versatile intermediate for advanced material synthesis. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as by manufacturers of impact modifiers and compatibilizers for polymer blends.

Application

• Adhesive & Sealant Formulations: Acts as a key tackifier and adhesion promoter, particularly for bonding to difficult substrates.
• Coatings & Inks: Used as a resin modifier to improve flexibility, chemical resistance, and pigment wetting in solvent-based and high-solid coatings.
• Polymer Modification: Serves as an impact modifier for engineering plastics and a compatibilizer for polymer alloys and blends.
• Elastomer Production: Incorporated into rubber compounds to enhance processability, filler dispersion, and crosslinking density.
• Foundry & Composite Resins: Used in binder systems for sand cores and as a reactive diluent or modifier in unsaturated polyester resins.
• Asphalt Modification: Improves the elasticity, cohesion, and aging resistance of asphalt for road paving and roofing applications.
