Description

4-tert-Butylstyrene is a high-purity aromatic monomer featuring a reactive vinyl group and a bulky tert-butyl substituent. This unique structure makes it a valuable intermediate for synthesizing specialty polymers with enhanced thermal stability, hydrophobicity, and tailored mechanical properties. It is essential for R&D chemists and production engineers in the advanced materials, coatings, and specialty chemical sectors seeking to modify polymer backbones for specific performance characteristics.

Application

• Specialty Polymer Synthesis: Key monomer for producing modified polystyrene, polyesters, and acrylic resins with improved heat resistance and solubility parameters.
• Advanced Coatings & Adhesives: Used to formulate high-performance industrial coatings, pressure-sensitive adhesives, and sealants requiring enhanced weatherability and chemical resistance.
• Ion-Exchange & Functional Resins: Serves as a precursor for manufacturing specialty ion-exchange resins and adsorbents used in water treatment and purification processes.
• Photoresist & Electronic Materials: Employed in the development of photoresist polymers and dielectric materials for the semiconductor and microelectronics industries.
• Organic Synthesis Intermediate: A versatile building block for pharmaceutical intermediates, agrochemicals, and liquid crystal compounds.
• Crosslinking Agent: Functions as a co-monomer to introduce crosslinking sites, improving the hardness and durability of cured polymer networks.

Quality Control

Our 4-tert-Butylstyrene is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen) to prevent oxidation and polymerization. Keep away from heat, sparks, and open flames. For long-term storage, monitor inhibitor content as specified.
