How is Perspex manufactured?

Answer 1

Poly(methyl methacrylate) (PMMA) or poly(methyl 2-methylpropenoate) is a thermoplastic and transparent plastic. Chemically, it is the synthetic polymer of methyl methacrylate. It is sold by the tradenames Plexiglas, Limacryl, R-Cast, Perspex, Plazcryl, Acrylex, Acrylite, Acrylplast, Altuglas, Polycast, Oroglass and Lucite and is commonly called acrylic glass or simply acrylic. Acrylic, or acrylic fiber, can also refer to polymers or copolymers containing polyacrylonitrile. The material was developed in 1928 in various laboratories and was brought to market in 1933 by Rohm and Haas Company. PMMA is often used as an alternative to glass, and in competition with polycarbonate (PC). It is often preferred because of its moderate properties, easy handling and processing, and low cost, but behaves in a brittle manner when loaded, especially under an impact force. To produce 1 kg of PMMA, about 2 kg of petroleum is needed. In the presence of oxygen

Answer 2

Perspex, also known as acrylic glass, is manufactured through a process called polymerization. It involves combining acrylic acid or its derivatives with other chemicals to form long chains of molecules. These molecules are then heated and molded into sheets or other shapes to create the final product.

Answer 3

Perspex is made by polymerizing Methyl Methacrylate in a cell constructed from two sheets of glass separated by a rubber ring.
