Poly(methyl methacrylate)

Poly (methyl methacrylate) can be synthesized into controlled living polymers via hours-long atom transfer radical polymerization; its hydrolysis performance is regulated by stereostructure; products from radical polymerization undergo thermal decomposition at 220 ℃, while products from anionic polymerization exhibit higher heat resistance, and the main thermal decomposition product of both types of materials is methyl methacrylate; in a toluene/methanol mixed solvent at 200 ℃, this polymer can react with primary amines to form polyglutarimide^[2].
Poly (methyl methacrylate) can be used to prepare a nanocomposite system via in-situ polymerization with dispersed multi-walled carbon nanotubes. The volume conductivity of the material increases by up to 10⁶ orders of magnitude, converting the insulating substrate into a semiconductor material^[2].
Poly (methyl methacrylate) can be used to prepare gel polymer electrolytes suitable for lithium-ion batteries; its reduced graphene oxide composite fiber coating exhibits higher ammonia detection sensitivity than single-component coatings, and this system can be applied to ammonia sensing; modification of TiO₂ photoanodes with composite NaGdF₄:Eu down-conversion layers increases the photoelectric conversion efficiency of dye-sensitized solar cells by 4.5%; the silica composite system prepared via two-step modified polymerization shows 80.6% and 127.3% increases in tensile and flexural strength, respectively, compared with pure samples^[2].
Poly (methyl methacrylate) exhibits better biocompatibility than cold-cured PMMA, with lower residual monomer elution and cytotoxicity; prolonging curing time and water soaking treatment can further reduce its cytotoxicity; it also possesses superior water-related physical properties, including low water absorption (0.69 mg/cm²), low water solubility (0.02 mg/cm² in water) and low thermal conductivity^[3].
Poly (methyl methacrylate) exhibits excellent mechanical properties, lower adhesion to Candida albicans, and comparable biocompatibility. It enhances mechanical properties such as Vickers hardness, flexural strength, and fracture toughness, making it more suitable for dental restoration applications^[3].
Poly (methyl methacrylate) (following 24 h microbial incubation) exhibits significant antibacterial activity against oral pathogenic bacteria, while maintaining good biocompatibility with L929 cells^[3].
