Synthesis and properties of novel polyurethane acrylate containing 3-(2-hydroxyethyl) isocyanurate segment

摘要

Hard coatings, eg polyurethane acrylates, are finding increasing use in optical and electrical applications. The hardness of the film is influenced by the crosslink density, chain flexibility and monomer rigidity. In this article, a novel UV curable polyurethane acrylate is synthesised, comprising a 3-(2-hydroxyethyl) isocyanurate (THEIC) segment.
