Его химическая формула - C₅H₈O₂ (structural formula: CH₂=C(CH₃)COOCH₃) and CAS number is 80-62-6. As a high-value vinyl monomer, MMA has excellent polymerization reactivity and is the core raw material for producing polymethyl methacrylate (PMMA, also known as acrylic glass). It is widely used in the plastics, coatings, and electronics industries due to its outstanding transparency, weather resistance, and mechanical properties.

Ключевые приложения

Polymethyl Methacrylate (PMMA) Production (Primary Use): MMA polymerizes to form PMMA, a transparent thermoplastic known as acrylic glass. PMMA is widely used in automotive light covers, building skylights, display panels, optical lenses, and consumer electronics (e.g., smartphone screens) due to its high light transmittance (92%), weather resistance, and impact resistance.

Coatings & Adhesives: MMA is a key monomer for water-based acrylic coatings, which are used in architectural coatings, automotive refinishing, and industrial anticorrosive coatings. It improves coating adhesion, gloss, and scratch resistance. MMA-based adhesives are applied in bonding plastics, metals, and glass.

Copolymers & Modified Resins: Copolymerization of MMA with styrene produces styrene-methyl methacrylate (SMMA) resins, which have higher heat resistance than polystyrene and are used in household appliances and packaging materials. Copolymerization with vinyl chloride improves the processing performance and toughness of PVC products.

Другие виды использования: MMA is used in the production of denture materials (dental acrylic resins) due to its biocompatibility and moldability. It is also applied in UV-curable inks, 3D printing resins, and textile sizing agents.
