Description

2-Butenedioic Acid (E)-, Polymer With 1,1'-[(1-Methylethylidene)Bis(4,1-Phenyleneoxy)]Bis[2-Propanol] is a specialized polymeric material formed from fumaric acid and a bisphenol A ethoxylate derivative. This product is valued for its role as a reactive intermediate or property-modifying component in advanced polymer synthesis. It is primarily sought by manufacturers in the coatings, adhesives, and specialty resin industries seeking to enhance material performance characteristics such as flexibility, adhesion, and chemical resistance.

Application

• As a key monomer or co-monomer in the synthesis of high-performance unsaturated polyester resins.
• Modifier for epoxy resin systems to tailor crosslink density and improve toughness.
• Component in radiation-curable coatings and inks, contributing to film formation and durability.
• Used in the formulation of industrial and construction adhesives.
• Intermediate for producing specialty polyols for polyurethane applications.
• Potential use in composite materials and fiber-reinforced plastics.

Quality Control

Our production of this polymeric material adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. While typically supplied as a technical grade polymer, specifications for key parameters such as acid value, hydroxyl value, viscosity, and glass transition temperature (Tg) are rigorously controlled. A Certificate of Analysis (COA) detailing these specifications is provided with each shipment.

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). Keep away from strong oxidizing agents and bases. Under these conditions, the product is typically stable for extended periods.
