Synthesis, Thermal Behaviour, and Antimicrobial Activity of Polyetherketones Based on p-Chloroanisol

Low molecular weight Friedel-Crafts polyetherketones were synthesized from pchloroanisole, 1,4-phenylenedioxy diacetylchloride, chloroacetylchloride, 1,2-dichloroethane, and dichloromethane in the presence of anhydrous aluminium chloride and carbon disulfide. The polymer samples were characterized by IR spectral study. The percentage of chlorine content of the resins was determined by the method of Carius.The molecular weights and polydispersities of the resins were obtained by gel permeationchromatography. Thermogravimetric analysis and differential scanning calorimetry wereemployed to study the thermal properties. All the polyetherketones were tested for theirbiological activity against bacteria, fungi, and yeast. It was observed that polyetherketonescould inhibit the growth of the microorganisms to a considerable extent.
