HEAT RESISTANT TRANSPARENT STYRENE-BASED RESIN WITH HIGH CHEMICAL RESISTANCE AND MOISTURE RESISTANCE, AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: A styrene-based resin is provided to remarkably improve chemical resistance and moisture absorption resistance, to maintain heat resistance, transparency, and workability, and to be used for optical materials and display materials. CONSTITUTION: A styrene-based resin includes a styrene-based repeating unit, a (meth)acrylic acid-based repeating unit, and a cycloalkyl (meth)acrylate-based repeating unit. The content ratio of the styrene-based repeating unit: (meth)acrylic acid-based repeating unit: cycloalkyl (meth)acrylate-based repeating unit is 70 ~ 90 : 5 ~ 15 : 5 ~ 15. The styrene-based repeating unit is selected from a group comprising styrene, α-methylstyrene, p-bromostyrene, p-methylstryene, p-chlorostyrene, and o-bromostryene.
