POLYARYLATE RESIN AND METHOD OF PREPARING THE RESIN, AND FIBER INCLUDING THE POLYARYLATE RESIN AND METHOD OF PREPARING THE FIBER

摘要

PURPOSE: A polyacrylate resin is provided to provide a polyaryltate fiber with high elasticity and high strength, while maintaining chemical resistance and flame retardance. CONSTITUTION: A polyacrylate resin comprises a repeating unit derived from a hydroxy benzoic acid-based compound; a repeating unit derived from a hydroxy naphthoic acid compound; and a repeating unit derived from a bisphenol-based compound. The molar ratio of the repeating units is 70-80:20-30:1-5 by parts by mole. The polyacrylate resin has a glass transition temperature of 200°C or more and melting temperature of 310-330°C. A polyacrylate fiber includes the polyacrylate resin.
