  • Publication number: 20120130041
    Abstract: The present disclosure relates to a transparent polyarylene ether polymer with high heat resistance and a method for preparing the same. More particularly, the present disclosure relates to a polyarylene ether polymer and a method for preparing the same, wherein the polyarylene ether polymer has a repeating structure in which cardo-type aromatic diols having a large molecular volume, polyether sulfones which are amorphous polymers having a high glass transition temperature and superior film formability, and polyether ketones which are crystalline polymers having superior heat resistance and mechanical properties are sequentially arranged. The polyarylene ether polymer is both transparent and heat resistant and, thus, can be used, for example, for a flexible plastic substrate.
