Description

2-Butenedioic Acid (2Z)-, Dibutyl Ester, Polymer With 1-Ethenyl-2-Pyrrolidinone is a specialized copolymer designed for advanced material science applications. This polymer combines the properties of a fumarate derivative with the excellent film-forming and adhesion characteristics of polyvinylpyrrolidone (PVP). It is engineered for formulators seeking to enhance the performance and stability of coatings, adhesives, and other polymer matrices.

Application

As a film-forming agent and binder in specialty coatings and paints.
As a dispersant and stabilizer for pigments and inorganic particles in aqueous systems.
In the formulation of adhesives and sealants to improve adhesion and flexibility.
As a modifier for synthetic resins to alter solubility, compatibility, or rheological properties.
In hair care and personal care products as a styling polymer or fixative resin.
Potential use in pharmaceutical applications as an excipient for controlled-release formulations.
As an additive in printing inks to improve gloss, rub resistance, and substrate adhesion.

Quality Control

Our production of this copolymer adheres to strict quality management protocols. Each batch is characterized for critical parameters including monomer ratio, molecular weight distribution, and residual monomer content to ensure consistent performance. Comprehensive Certificates of Analysis (COA) detailing specifications and test results are provided with every 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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent moisture absorption, which may affect product properties.
