Synthesis and Modification of New Phenolic Resins Bearing Pendant 1,8-Naphthalimides
Ahlam Marouf Al-Azzawi [4] | Esraa Faiq
Abstract: Four new phenol-formaldehyde resins bearing 1, 8-naphthalimides in their repeating units were synthesized via condensation of formaldehyde with N- (hydroxy phenyl) -1, 8-naphthalimides under conditions similar to these used in novolac preparation. In this work structural modifications were performed first via synthesis of new phenolic component represented by phenolic ring linked to thermally stable 1, 8-naphthalimide moiety which condensed with formaldehyde and second by introducing of phenolic hydroxyl groups present in the newly synthesized resins in esterification reaction with benzoyl chloride producing the corresponding benzoyloxy substituted resins. Both the synthesized and the cured resins have new properties which may serve different applications.
