NOVEL POLYARYLATE AND METHOD FOR PREPARATION THEREOF

摘要

The present invention relates to a polyarylate prepared by a method comprising a step of copolymerizing divalent phenol, divalent aromatic carboxylic acid halide and the allyl bisphenol derivative. The polyarylate according to the invention is a novel polyarylate in which various functional groups can be introduced to the main chain of the polymer as well as the terminal of a polymer, and the concentration thereof can be adjusted. These functional groups allow im¬ provement in the adhesion force by chemically bonding with the substrate or protective layer when coated, thus the polyarylate is suitably used for a film or a coating composition.
