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

Low molecular weight Friedel-Crafts polyetherketones were synthesized from pchloroanisole, 1,4-phenylenedioxy diacetylchloride, chloroacetylchloride, 1,2dichloroethane, 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 permeation chromatography. Thermogravimetric analysis and differential scanning calorimetry were employed to study the thermal properties. All the polyetherketones were tested for their biological activity against bacteria, fungi, and yeast. It was observed that polyetherketones could inhibit the growth of the microorganisms to a considerable extent.
