POLYARYLATE RESIN
Document Type and Number:
Japanese Patent JP2018070726
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polyarylate resin capable of molded at comparatively low temperature compared to a conventional one while keeping heat resistance, transparency and mechanical physical properties inherent to the polyarylate resin.SOLUTION: There are provided a polyarylate resin which contains a divalent phenol residue and an aromatic divalent carboxylic acid residue as main components and has a monovalent carboxylic acid residue represented by general formula (1) in its terminal; the polyarylate resin, where the monovalent carboxylic acid residue represented by general formula (1) is 10.0-18.0 mol% with respect to the wholly aromatic divalent carboxylic acid residue; and the polyarylate resin, where the monovalent carboxylic acid residue represented by general formula (1) is a stearic acid residue or an isostearic acid residue. General formula (1): -CO-X, in general formula (1), X represents a straight or branched alkyl group having 15 to 28 carbon atoms.SELECTED DRAWING: None
