Exposure of transparent solids, both glasses and crystals, to high-energy radiation frequently makes them colored. The defects responsible for this are known as color centers. The first of these defects to be characterized was the F center, a term derived from the German Farbzentrum (color center). 

Theses polymers are made from acrylic acid, its homologues and their derivatives. Glass like resins were made from esters of aerylic acid in 1877 by Fitting and Peter by Kahlbaum. In 1928, Rohm and Hass, a German Company started commercial development of methacrylic esters. Limited production started in 1933. The rapidly expanding air-force used this plastic in place of glass in the aeroplanes. Most of the early production of "Plexiglass was used up by air-force planes. In 1936, ICI marketed methyl methacrylate sheets as "Perspex".
