摘要：

The copolyesters of poly(butylene terephthalate) and poly(butylene adipate) were prepared by melt polycondensation of 1,4‐butanediol, terephthalic acid, and adipic acid. The thermal stability was important for their use a shot melt adhesives. The thermal degradation of these copolysters and homopolyesters was determined through TGA, change of acid number, IR, GPC, and NMR analyses. It was found that the thermal stability of the copolysters in oxygen decreased as the content of butylene adipate increased at temperature above and below Tm. Thermal degradation occured in oxygen even at temperature lower than Tm, so that degradation would also occur at room temperature in air and embrittlement was found for these copolysters for long term service.
