HIGH REFRACTIVE INDEX ACRYLIC COMPOUND AND METHOD FOR PREPARING THE SAME

摘要

An acrylic compound is represented by Formula 1.;;In Formula 1, R1 and R2 are each independently a C2 to C10 alkylene group, a C6 to C20 arylene group, a C7 to C20 alkylarylene group, or a C7 to C20 arylalkylene group. Ar1 is a C6 to C10 aryl group. X1 and X2 are each independently —O— or —S—. Y1 and Y2 are each independently a hydrogen atom, —OH, —SH, —NH2,;;and at least one of Y1 and Y2 is;;n1, n2, n3 and n4 are each independently 1 to 4 on average. The acrylic compound includes no halogen atoms and has a high refractive index of about 1.65 or greater.
