Methyl methacrylate to Poly(methyl methacrylate)

Methyl methacrylate is produced in industrial buisnesses such as Lucite internationals, this monomer is then turned into polymer through a process called polymerisation this changes methyl methacrylate into perspex (also known as Lucite)

perspex is illerstrated in the chemical representation above.

Perspex was used in the B-17G WW2 American bomber, this was the first time Plexiglass was used in a large scale in 1943
