Notes:
Allyl diglycol carbonate (CR39)® is a thermosetting polymer of interest both as an ophthalmic material and as a material intermediate between brittle and ductile solids. The response to impact in the crack-threshold range has been studied and compared to that of glass. The energy absorbed upon impact, the plastic deformation, and the crack resistance are all found to be greater for CR39, and the relationships between these factors are discussed. The developments of impact response for CR39 with increasing temperature and increasing impact energy beyond the crack-threshold range have also been studied.
