“…They are generally synthesized by repeated reactions of multifunctional monomers, mostly AB 2 type monomers. UV curable oligomers based on amine–ester, ester–amide, and ether–amide with AB 2 type monomers have been prepared by the authors 8–10. However, the UV cured films from those materials are all flammable when attacked by a fire without addition of other flame retardants.…”

A series of hyperbranched polyurethane acrylates containing phosphorus were prepared by reaction of a phosphorus‐containing triol with toluene‐2,4‐diisocyanate and hydroxylethyl acrylate at given ratios. The resins obtained were found to polymerize rapidly in the presence of a photofragmenting initiator under UV irradiation, and the maximum polymerization rate increased with temperature up to 125 °C, then decreased quickly. The UV cured films have flame retardancy with a limiting oxygen index of 27.0. © 2002 Society of Chemical Industry

Ultraviolet (UV)-curing behavior of an epoxy acrylate resin system comprising an epoxy acrylate oligomer, a reactive diluent, and a photoinitiator was investigated by Fourier transform infrared (FTIR) spectroscopy. The conversion changes of the resin system containing 20 phr of 1,6-hexanediol diacrylate as a reactive diluent and 2-hydroxy-2-methyl-1-phenyl-propan-1-one as a photoinitiator were measured under different UV-curing conditions. The fractional conversion was calculated from the area of the absorption peak for the vinyl group vibration occurring at 810 cm Ϫ1 . The effects of photoinitiator concentration, total UV dosage, one-step or stepwise UV irradiation, UV intensity, atmosphere, and temperature on the curing behavior of the resin system were investigated. The conversion of the resin system increased rapidly at the initial stage of the UV-curing process but increased very slowly after that. The final conversion of the resin system was mainly affected by total UV dosage.

“…[1][2][3][4][5][6][7][8][9][10][11][12] Coatings that are abrasion resistant and require short cure time are much desired. The acrylic monomer/oligomer is an important UV-curable resin widely used for coatings because of its excellent optical properties and easy processability.…”

An organic-inorganic hybrid polymeric nanocomposite has been synthesized for making UV-curable hard coats. This nanocomposite consists of nano-sized colloidal silica functionalized with vinyltriethoxysilane (VTES) and dendritic acrylic oligomers (DAO) which have been formed earlier via a reaction of ethylenediamine (EDA) with trimethylopropane triacrylate (TMPTA). Applied as a hard coat on top of a polyethylene terephthalate (PET) film, this nanocomposite has a short UV-cure time and the cured coat has an enhanced thermal decompo-sition temperature (T d ), 89-90% transparency, increased hardness up to 3H, better adhesion up to 4B, and a flat surface with a root mean square roughness of 2-4 nm. The preparation as well as the characterization of the constituting species and the final hybrid are described in detail.
