physical and chemical properties of pmma

Polyesters display a wide array of properties and practical applications. For example, poly(cyclohexyl methacrylate) finds uses in adhesives, binders, and coatings. Comprising a unique set of chemical and physical properties makes it suitable over glass, PMMA and PE. Due to their ability to change their refractive index with temperature as in the case of PMMA and HEMA: MMA, they are used in lasers for applications in spectroscopy and analytical applications.

GENERAL DESCRIPTION Acrylics (Polymethyl-Methacrylate or PMMA) is an amorphous thermoplastic which is optically transparent, unaffected by moisture, and offers a high strength-to-weight ratio. Along with the mechanical properties (fracture toughness (KIC), flexural strength (FS), and flexural modulus (FM)) of the reinforced cements the following properties were investigated: complex viscosity-versus-time, maximum polymerization temperature (Tmax), dough time (tdough), setting time (tset), radiopacity, and in vitro biocompatibility. The luminescent properties of two types of dye-poly(methyl methacrylate) (PMMA) composite nanospheres were discussed and compared. A larger number of other polymethacrylates are commercially available.
