Description

Poly(4-Methylstyrene/Styrene) is a high-performance copolymer engineered by combining styrene with 4-methylstyrene monomers. This material offers a unique balance of thermal stability, processability, and tailored physical properties compared to standard polystyrene. It is a critical raw material for industries requiring specialized polymer performance, particularly in advanced plastics, coatings, and resin modification. The compound is identified by CAS No. 24936-42-3.

Application

• High-Performance Plastics & Resins: Used as a base polymer or modifier to enhance heat resistance, dimensional stability, and mechanical strength in engineering plastics.
• Specialty Coatings & Adhesives: Serves as a key component in formulating high-gloss, durable industrial coatings, sealants, and pressure-sensitive adhesives.
• Optical Materials: Employed in the production of lenses, light guides, and other optical components due to its potential for clarity and refractive index tuning.
• Toners & Printing Inks: Acts as a binder resin to improve fusing properties, image quality, and durability in electrophotographic toners and specialty inks.
• Polymer Modification: Used as an additive or compatibilizer to improve the impact strength, flow characteristics, and surface properties of other polymer blends.
• Laboratory & Research: Utilized as a standard or custom polymer for material science research, chromatography media, and polymer reaction studies.
