Description

2-Butenedioic Acid (E)-, Polymer With 1,2-Ethanediol is a polymeric ester derived from fumaric acid and ethylene glycol. This specialized polymer is valued for its role as a functional intermediate and building block in advanced material synthesis. It is primarily sought by manufacturers in the polymer, coatings, and specialty chemical industries for developing resins, plasticizers, and performance additives with tailored properties.

Application

• Polymer & Resin Modification: Acts as a reactive intermediate or cross-linking agent in the production of unsaturated polyester resins (UPRs) and alkyd resins.
• Coating Formulations: Used to enhance the durability, flexibility, and chemical resistance of industrial and protective coatings.
• Specialty Plasticizers: Serves as a precursor for synthesizing polymeric plasticizers that offer low volatility and improved permanence in PVC and other polymer systems.
• Adhesive & Sealant Systems: Incorporated to modify rheology and improve adhesion properties in high-performance formulations.
• Biomedical Materials: Potential use as a biodegradable polymer component in controlled-release drug delivery systems or tissue engineering scaffolds.
• Composite Materials: Functions as a matrix resin or compatibilizer in fiber-reinforced composites and advanced material blends.

Quality Control

Our production of 2-Butenedioic Acid (E)-, Polymer With 1,2-Ethanediol adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency in molecular weight distribution, acid value, and functional group content. Certificates of Analysis (COA) detailing specific parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and incompatible materials. Due to its polymeric and potentially hygroscopic nature, prolonged exposure to high humidity should be avoided to maintain product integrity.
