Poly(allyl diglycol carbonate) (PADC) is a plastic commonly used in the manufacture of eyeglass lenses alongside the material PMMA (polymethyl methacrylate). The monomer is allyl diglycol carbonate (ADC). The term CR-39 technically refers to the ADC monomer, but is more commonly used to refer to the finished plastic. The abbreviation stands for "Columbia Resin #39", which was the 39th formula of a thermosetting plastic developed by the Columbia Resins project in 1940.

  • CR-39 или аллилдигликолькарбонат (АДК) — пластик, широко используемый в качестве материала линз для очков. Аббревиатура CR обозначает название проекта разработки термоактивных пластмасс — «Columbia Resin», в котором формула АДК была тридцать девятой по счёту. CR-39 также используется в дозиметрии для измерения одного из видов ионизирующего излучения — нейтронного излучения. Не следует путать CR-39 с поликарбонатом — упругим гомополимером, получаемым из бисфенола А. (ru)
