Synthesis and properties of isocyanate-functionalized isosorbide high heat-resistant copolyesters
Key Points
Isocyanate-functionalization leads to enhanced heat resistance in copolyesters.
The modified copolyesters exhibit improved thermal properties as confirmed by analysis.
The approach utilizes conventional poly(ethylene glycol-1,4-cyclohexanedimethanol terephthalate) for effective modifications.
Potential applications may include advanced materials for high-temperature environments.
Abstract
In this work, conventional poly(ethylene glycol-1,4-cyclohexanedimethanol terephthalate) (PCTG) was modified by functionalizing isosorbide (ISB) with isophorone diisocyanate (IPDI).
