SYNTHESIS AND BIOLOGICAL-ACTIVITY OF CHLORINE-CONTAINING POLYKETONES

Chlorine-containing polyketones of low molecular weight were synthesiz ed from anisole, chloroacetyl chloride and dichloroalkanes, i.e. dichl oromethane and 1,2-dichloroethane, by the Friedel-Crafts reaction usin g carbon disulfide as solvent. The resins were characterized by IR spe ctra and vapour pressure osmometry. The thermal properties were studie d by thermogravimetry and differential scanning calorimetry. The chara cteristics of the decomposition reactions were evaluated by the Broido and Doyle methods. All the resins were tested for their microbial act ivity against bacteria, fungi and yeast. The results show that most of the resins can be used as biocides.
