Tag: Copolyester

Nine copolyesters were prepared from a dicarboxylic acid, curcumin analogues (monocarbonyl) and phenophthalene dye in the mole ratio of 2:1:1 by direct polycondensation using triethylamine (Et3N) as the condensation agent. The dicarboxylic used is 2,6-Pyridine dicarbonyl dichloride acid. The curcumin analogues were prepared by acid catalyzed Aldol condensation reaction. These…

Antibiotic resistance occurs when microorganisms develop mechanisms that protect them from the effects of antibiotics. Resistant microorganisms are more difficult to treat, require higher doses or alternative therapies may be more toxic, as well as more expensive. Microorganisms that are able to resist many antibiotics are called multi-resistant. All kinds…
