Triethylene Glycol → Urethane acrylate

Participants

Reaction Steps

2 moles of isophorone diisocyanate, 1 mole of triethylene glycol, and 2 moles of 2-hydroxyethyl acrylate were reacted by a predetermined method so as to yield urethane acrylate as a monomer of a ultraviolet-curing resin. Subsequently, a monomeric composition was prepared by mixing 50 grams of the urethane acrylate, 25 grams of the acrylic ester compound obtained in Example 1, 25 grams of 1,6-hexanediol diacrylate as a monomer of the ultraviolet-curing resin, and 3 grams of benzylmethyl ketal as a photopolymerization initiator (produced by Ciba-Geigy and marketed under the trade name "Irgacure 651").
