Poly(acrylic acid) (CAS NO.9003-01-4) is widely used because of their clarity, brilliance, ease of forming, and light weight. It has excellent optical properties and is used for camera, instrument, and spectacle lenses. Because of their excellent dielectric strength PAA(9003-01-4) is often used for high-voltage line spacers and cable clamps.
The methyl, ethyl, and butyl esters of acrylic and methacrylic acids are polymerized under the influence of heat, light, and peroxides. The polymerization reaction is exothermic and may be carried out in bulk for castings, or by emulsion, or in solution.
