A photocurable 1,4:3,6-dianhydro-D-hexane-1,2,3,4,5,6-hexol derivative, a preparation method thereof and a photocurable composition comprising the same

摘要

PURPOSE: A photocurable isosorbide derivative and a method for preparing the same are provided to replace bisphenol A photocurable materials and to reduce irreversible carbon dioxide generation. CONSTITUTION: A photocurable isosorbide derivative is denoted by chemical formula 1. A method for preparing the compound of chemical formula 1 comprises: a step of reaction of a compound of chemical formula 1 and epibromohydrine under the presence of hydroxide salt using a aprotic polar solvent to prepare a compound of chemical formula 3; and a step of reacting methacrylic acid with the compound of chemical formula 3 to prepare a compound of chemical formula 1. The compound of chemical formula 2 is derived from carbohydrate polymers. The aprotic polar solvent is DMSO, DMF, DMA, or NMP. A photocurable composition contains the compound of chemical formula 1 and free radical photo initiator.
