| titleOfInvention | Polyester copolymer for heat-resistant molding material |
| abstract | PURPOSE: To obtain a polyester copolymer having excellent heat-resistance, dimensional stability, mechanical strength and moldability by copolymerizing an aromatic dicarboxylic acid component with a specific glycol component. n CONSTITUTION: The objective polyester copolymer suitable as a heat-resistant resin durable to soldering work is produced by carrying out ester interchange reaction of (A) a glycol component containing (a) 1,4-cyclohexanedimethanol having a trans-content of ≥80% and (b) ethylene glycol at a ratio defined by the formula (Ma is molar ratio of 1,4-cyclohexanedimethanol in the polymer; Mb is molar ratio of ethylene glycol in the polymer) and (B) an aromatic dicarboxylic acid component (preferably tetraphthalic acid or dimethyl terephthalate) and carrying out polycondensation reaction in high vacuum. n COPYRIGHT: (C)1990,JPO&Japio |
