POLY(ARYLENE ETHER) WITH TRANSPARENCY AND HIGH HEAT-RESISTANCE AND THE SYNTHESIS THEREOF

摘要

PURPOSE: A poly(arylene ether)-based polymer is provided to ensure excellent transparency and heat resistance and to enable the application to flexible plastic substrate materials for a roll type display, solar cell, and electronic paper. CONSTITUTION: A polyarylene ether polymer has a repeating structure of chemical formula (1a) or (1b) in which cardo-based aromatic diols having a large molecular volume, polyether sulfones which are amorphous polymers having a high glass transition temperature and excellent film formability, and polyether ketones which are crystalline polymers having superior heat resistance and mechanical properties are sequentially arranged.
