How are synthetic plastics made

WebSynthetic casting "resin" for embedding display objects in Plexiglas/Lucite ( PMMA) is simply methyl methacrylate liquid, into which a polymerization catalyst is added and mixed, causing it to "set" (polymerize). The polymerization creates a block of PMMA plastic ("acrylic glass") which holds the display object inside a transparent block.
