| titleOfInvention | Copolyester for heat-resistant packaging material |
| abstract | PURPOSE: To improve heat resistance, gas barrier property, transparency and mechanical strengths by using a specific compd. as a comonomer. n CONSTITUTION: By copolymerizing an acid component contg. at least 80mole% terephthalic acid, a glycol component contg. at least 80mole% ethylene glycol, and 3-20mole% (based on said acid component) compd. of the formula (wherein R 1 and R 2 are each H or 1-3C alkyl; R 3 is H, or 1-10C alkyl, aralkyl or aryl), a copolyester for heat-resistant packaging material with a glass transition temperature of 83-90°C and an intrinsic viscosity (in a mixed solvent of phenol/ tetrachloroethane in a wt. ratio of 60/40, 35°C) of 0.4-1.0 is produced. n COPYRIGHT: (C)1990,JPO&Japio |
