| Abstract | ||||
| SATURATED copolyesters were prepared by polyesterification of bisphenol-A (BPA) and phthalic anhydride or tetrabromophthalic anhydride with ethylene glycol, diethylene glycol, 1,3-propanediol, 1,5-pentanediol, 1,6-hexanediol, and cis-2-butene-1,4-diol. Also, unsaturated copolyesters were prepared by polyesterification of bisphenol-A and maleic anhydride with the same glycols. All the copolyester resins obtained have been characterized; unsaturated copolyesters were found to cure with styrene. The properties of the copolyester in the form of films were determined. Also, the fire retardancy of polyesters was evaluated as varnish films on plywood strips. IR and 1HNMR spectroscopy were used for characterization of the copolyester resins. The antimicrobial activity of the copolyesters obtained was examined against gram-positive and gram-negative bacteria. | ||||
