SYNTHESIS AND CHARACTERIZATION OF UV-CURABLE ACRYLATED URETHANE PREPOLYMERS .1. EFFECTS OF REACTIVE DILUENTS AND RELATIVE-HUMIDITY ON PHYSICAL-PROPERTIES

Description

A UV-curable acrylated urethane prepolymer was synthesized from tolylene-2,4-diisocyanate (TDI), a polyether polyol (Arcol 1131) and endcapped with 2-hydroxyethyl methacrylate (HEMA) by addition reaction in the presence of dibutyltin dilaurate as catalyst. UV curing was performed with either diethylene glycol diacrylate or thiodiethylene glycol diacrylate as reactive diluent.
