摘要

<正>In this work, two new diacids, di（m-carboxyphenyl） succinate （m-dCPS） and di（o-carboxyphenyl） succinate （o-dCPS）, were synthesized by reaction of m-, o-hydroxy benzoic acid with succinic chloride, respectively. Their corresponding copolymers with sebacic acid （SA）, P（m-dCPS:SA） and P（o-dCPS:SA）, were prepared by melt copolycondensation and characterized by NMR, UV and DSC methods. Compared with inherently fluorescent poly[di（p-carboxyphenyl） succinate-co-sebacic anhydride] （P（p-dCPS:SA））, P（m-dCPS:SA） and P（o-dCPS:SA） displayed different luminescent properties. P（m-dCPS:SA） could emit fluorescence under the excitation of both visible and UV light, while P（o-dCPS:SA） could only emit fluorescence when excited with UV light. Degradation rate of the two new copolyanhydrides increased with the increase of SA fraction in the copolymers. In addition, P（o-dCPS:SA） degraded more rapidly than P（m-dCPS:SA） with the same composition. Typical surface-degradation characteristics of these copolyanhydrides were observed.

Abstract

In this work, two new diacids, di（m-carboxyphenyl） succinate （m-dCPS） and di（o-carboxyphenyl） succinate （o-dCPS）, were synthesized by reaction of m-, o-hydroxy benzoic acid with succinic chloride, respectively. Their corresponding copolymers with sebacic acid （SA）, P（m-dCPS:SA） and P（o-dCPS:SA）, were prepared by melt copolycondensation and characterized by NMR, UV and DSC methods. Compared with inherently fluorescent poly[di（p-carboxyphenyl） succinate-co-sebacic anhydride] （P（p-dCPS:SA））, P（m-dCPS:SA） and P（o-dCPS:SA） displayed different luminescent properties. P（m-dCPS:SA） could emit fluorescence under the excitation of both visible and UV light, while P（o-dCPS:SA） could only emit fluorescence when excited with UV light. Degradation rate of the two new copolyanhydrides increased with the increase of SA fraction in the copolymers. In addition, P（o-dCPS:SA） degraded more rapidly than P（m-dCPS:SA） with the same composition. Typical surface-degradation characteristics of these copolyanhydrides were observed.
