| titleOfInvention | Aromatic polyester carbonate and production thereof |
| abstract | PURPOSE: To obtain the title polycarbonate giving an engineering plastic having low water-absorption and remarkably improved heat-resistance and oxidation stability without lowering the melt-formability and mechanical properties of the base resin, by substituting a residue composed mainly of hydroquinone with diphenol residue. n CONSTITUTION: The objective aromatic polyester carbonate having an intrinsic viscosity of ≥0.5 is a linear polymer composed mainly of the residues of formula I, II and III (Ar is group of formula IVWVI) wherein the ratios of the residues IWIII satisfy the formulas 30/70≤a/b≤90/10 and 0.8/1.2≤b/c≤1.2/0.8 (a, b and c are molar numbers of the residues I, II and III, respectively). The polyester carbonate can be produced by reacting an aromatic hydroxycarboxylic acid (or its ester-forming derivative) (e.g. p-hydroxybenzoic acid), 4,4'-diphenol, etc., and a diaryl carbonate. n COPYRIGHT: (C)1989,JPO&Japio |
