“…Seven low MW polyketones [73] were prepared by the Friedel-Crafts reaction from p-cresol, chloroacetyl chloride, and dichloroalkane (dichloromethan or 1,2-dichloroethane). The MWs of resulting polyketones were 2 320-2 485, and the ketones were soluble in common solvents.…”

“…Their property set is positioned in the area of polyamides and polyacetals. Friedel-Crafts polymers formed on polycondensation of 4,4 -dichloromethyldiphenyl ether with benzene, toluene, isomeric chlorotoluenes and xylenes, phenol and isomeric cresols have been reported (7)(8)(9). A considerable amount of research effort has concentrated on the synthesis of polyketones via Friedel-Crafts reaction (10)(11)(12)(13).…”

“…A considerable amount of research effort has concentrated on the synthesis of polyketones via Friedel-Crafts reaction (10)(11)(12)(13). The synthesis of such polymers is usually performed by Friedel-Crafts acylation or nucleophilic aromatic displacement, which has been a subject of research for a number of years (7)(8)(9)14). As a result, the preparation of various polyketones and investigations of their properties have been reported by many workers (10)(11)(12)(13)(14)(15)(16)(17).…”

Novel Friedel-Crafts polyketones containing naphthalene moiety were synthesized via the electrophilic Friedel-Crafts polycondensation method. The desired polyketones were obtained by the interaction of newly synthesized dinaphthylidenecycloalkanone monomers with different aliphatic and aromatic diacid chlorides. The structures of new monomers and polymers were confirmed by elemental and spectral analyses, besides X-ray single crystal data for the two new monomers. The new polyketones were characterized by solubility, viscometry, thermal properties, scanning electron microscopy and antimicrobial activity test. All the polyketones were soluble in formic acid as protonic solvent giving yellowish to brown colors. Some of the polyketones were partially soluble in n-hexane, benzene and chloroform. The thermal properties of those polymers were evaluated by TGA; DTG and DTA measurements. The desired polyketones have high thermal stability at T 10 except polymer 3 b which have low T 10 value. FDT for all polyketones is nearly completed at around 522-677 • C. The morphological properties of polyketone 2 b were tested by SEM measurements. The synthesized monomers and polymers were screened for their antibacterial and antifungal activities. They showed a moderated antibacterial activity against tested Gram-negative and Gram-positive bacteria and no significant influence against the selected fungi species except monomer 1 b and polymers 2 a , 3 b .

4‐Chloro‐3‐methyl phenyl methacrylate (CMPM) and 8‐quinolinyl methacrylate (8‐QMA) were synthesized through the reaction of 4‐chloro‐3‐methyl phenol and 8‐hydroxy quinoline, respectively, with methacryloyl chloride. The homopolymers and copolymers were prepared by free‐radical polymerization with azobisisobutyronitrile as the initiator at 70 °C. Copolymers of CMPM and 8‐QMA of different compositions were prepared. The monomers were characterized with IR spectroscopy and 1H NMR techniques. The copolymers were characterized with IR spectroscopy. UV spectroscopy was used to obtain the compositions of the copolymers. The monomer reactivity ratios were calculated with the Fineman–Ross method. The molecular weights and polydispersity values of the copolymers were determined with gel permeation chromatography. The thermal stability of the polymers was evaluated with thermogravimetric analysis under a nitrogen atmosphere. The homopolymers and copolymers were tested for their antimicrobial activity againstbacteria, fungi, and yeast. © 2004 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 43: 157–167, 2005
