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 … See more CR-39 is made by polymerization of ADC in presence of diisopropyl peroxydicarbonate (IPP) initiator. The presence of the allyl groups allows the polymer to form cross-links; thus, it is a thermoset resin. … See more Optics CR-39 is transparent in the visible spectrum and is almost completely opaque in the ultraviolet range. It has high abrasion resistance, … See more • Corrective lens See more WebJan 1, 1984 · The first positive detection of highly relativistic (not less than 7.5 GeV/n) cosmic ray iron nuclei, in the plastic CR-39 (Allyl Diglycol Carbonate), during a balloon flight made from Hyderabad ... curious george thanksgiving book
