Thermal analysis of polyester and polyamides based on vanillic acid derivat
ive - terephthaloyl-bis-(3-methoxy-4-oxy benzoic) acid has been reported. D
ifferent behaviours with the appearance of the thermal degradation, stuctur
ization and carbonization stages were detected.
Thermochemical behaviour of polymers under investigation revealed that tech
nical lignin derivative - vanillic acid are a promise for obtaining polymer
materials with good properties.
