Description

2-Propenoic Acid, 4-(4-Hydroxyphenoxy)Butyl Ester is a specialized acrylate ester monomer featuring a phenolic hydroxyl group, offering unique reactivity for polymer synthesis. This compound is valued for its ability to introduce both polymerizable acrylate functionality and pendant phenolic groups into polymer backbones, enabling the creation of materials with tailored properties. It is primarily sought by R&D chemists and material scientists in the polymer, coatings, and specialty chemical industries for developing advanced resins, photopolymers, and functional additives.

Application

• Photopolymer & UV-Curable Resins: Serves as a key monomer for formulating advanced UV-curable coatings, inks, and adhesives, where the phenolic group can enhance adhesion and modify cross-linking density.
• Specialty Acrylic Polymers: Used to synthesize functional acrylic copolymers with pendant phenolic moieties for applications requiring specific chemical resistance, thermal stability, or surface properties.
• Reactive Diluent & Modifier: Acts as a reactive diluent in epoxy-acrylate or urethane-acrylate hybrid systems, contributing to viscosity reduction while participating in the curing network.
• Adhesion Promoters: Incorporated into primer formulations to improve substrate adhesion, particularly on metallic or challenging surfaces, due to the polar phenolic functionality.
• Biomedical Material Synthesis: Investigated for creating biocompatible hydrogels or polymer scaffolds where the phenolic group allows for further chemical conjugation or provides antioxidant properties.
• Advanced Composite Materials: Utilized in the production of fiber-reinforced composites and engineering plastics to enhance interfacial bonding between the polymer matrix and reinforcing fibers.
