Interpenetrated hybrid thiol-ene/epoxy network were obtained via UV-induced polymerization. By combining the network structure derived from epoxy curing with that of thiol-ene system we could expect an important toughening effect due to the presence

A novel spiroorthocarbonate with two thiol groups (SOC DITHIOL) was synthesized. This monomer was formulated with dimethacrylate monomers used in dental resins and photopolymerized with an LED dental lamp. The presence of the thiol groups in the mono

A pair of novel tetrafunctional spiroorthocarbonates (TETRASOC) was prepared in three stages. First, glycerol was reacted with tetraethyl orthocarbonate to form a pair of isomeric hemi spiroorthocarbonates (HEMI SOC-OLs) by monocyclization of glycero

It is well known that bicyclic compounds like spiro-orthocarbonates (SOCs) have the ability to reduce or eliminate the shrinkage produced during polymerization. In the work reported, four different SOCs were prepared, two of them with one and two hyd
