Applications polyfmethyl methacrylate

The important features of rigidity and transparency make the material competitive with polystyrene, cellulose acetate and poly(methyl methacrylate) for a number of applications. In general the copolymer is cheaper than poly(methyl methacrylate) and cellulose acetate, tougher than polyfmethyl methacrylate) and polystyrene and superior in chemical and most physical properties to polystyrene and cellulose acetate. It does not have such a high transparency or such food weathering properties as poly(methyl methacrylate). As a result of these considerations the styrene-acrylonitrile copolymers have found applications for dials, knobs and covers for domestic appliances, electrical equipment and car equipment, for picnicware and housewares, and a number of other industrial and domestic applications with requirements somewhat more stringent than can be met by polystyrene. 

In particular, polymers are resilient and easy to fabricate and can be combined with specific drugs. Among many polymers, polyfmethyl methacrylate) and polyurethanes are highlighted due to their biocompatibility and the possibility to be used in several medical devices. PMMA is usually employed in bone tissue engineering, while PU has applications mainly in cardiovascular tissue engineering. Both polymers can be designed for a specific application, and they have already been used in the development of prostheses with controlled drug release.
