| 摘要 |
Copolyester-carbonates having amide and carbamate terminal groups. These copolyester-carbonates are prepared by reacting (i) a carbonate precursor, (ii) at least one difunctional carboxylic acid or an ester forming reactive derivative thereof, (iii) at least one dihydric phenol, and (iv) a chain terminating amount of at least one carbamate-amide precursor. These copolyester-carbonates exhibit improved thermal stability.
