polümetüülakrülaadi

Polümetüülakrülaat, often abbreviated as PMMA, is a transparent thermoplastic polymer. It is the synthetic polymer derived from the monomer methyl methacrylate. PMMA is known for its excellent optical clarity, rigidity, and weather resistance. It is often used as a lightweight and shatter-resistant alternative to glass. Industrially, it is produced through various polymerization processes, including bulk, solution, suspension, and emulsion polymerization. These methods influence the final properties of the polymer, such as molecular weight and chain architecture.

Common trade names for PMMA include Plexiglas, Lucite, and Acrylite. Its applications are widespread, ranging from automotive components like taillights to household goods, signage, and medical devices. Due to its transparency and ease of fabrication, it is also utilized in optical lenses, aquariums, and protective screens. PMMA can be molded, extruded, or cast into various shapes. While generally resistant to UV radiation and weathering, it can be susceptible to scratching and certain organic solvents. Recycling of PMMA is possible through mechanical or chemical processes, allowing for its reuse in new products.
