Description

1,3-Butadiene, Homopolymers, Oligomeric, Maleated is a functionalized oligomer where maleic anhydride groups are grafted onto a low molecular weight polybutadiene backbone. This chemical modification imparts enhanced polarity and reactivity, making it a valuable compatibilizer and adhesion promoter in polymer systems. It is primarily utilized by formulators in the adhesives, sealants, coatings, and polymer compounding industries to improve the interfacial bonding between dissimilar materials.

Application

• As a reactive compatibilizer in polymer blends and alloys, particularly for non-polar/polar combinations (e.g., polyolefin/polyamide).
• As an adhesion promoter in pressure-sensitive adhesives, sealants, and coatings for substrates like metals and treated plastics.
• As a toughening agent and impact modifier for engineering thermoplastics and thermosets.
• As a chemical intermediate for further synthesis, leveraging the reactivity of the maleic anhydride groups.
• As a viscosity modifier and flow enhancer in specialty lubricants and functional fluids.
• In the formulation of printing inks and toners to improve pigment dispersion and substrate adhesion.

Quality Control

Our 1,3-Butadiene, Homopolymers, Oligomeric, Maleated is manufactured under a strict quality management system. Each batch is characterized for key parameters including acid value (degree of maleation), molecular weight distribution, and viscosity to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture, which can affect product properties.
