Aromatic homopolymers obtained by precipitation polycondensation: 1. Synthesis of naphthalene-containing polyketones

High molecular weight film-forming semicrystalline aromatic polyketones with a regular structure were obtained by precipitation electrophilic Friedel-Crafts polycondensation of 2,6-naphthalenedicarboxylic acid chloride with diphenyl ether, 1,4-bis( p-phenoxy) benzophenone and 1,4-bis( p-phenoxybenzo...

Summary:High molecular weight film-forming semicrystalline aromatic polyketones with a regular structure were obtained by precipitation electrophilic Friedel-Crafts polycondensation of 2,6-naphthalenedicarboxylic acid chloride with diphenyl ether, 1,4-bis( p-phenoxy) benzophenone and 1,4-bis( p-phenoxybenzoyl) benzene. Using 1H and 13C n.m.r. spectroscopy, the polyketones obtained were shown to be linear with para-substituted arylene fragments in the main chain. These polymers are soluble in strong protic acids and in common organic solvents, such as dichloroacetic acid and CHCl 3/CF 3CO 2H mixtures. Depending on the chemical structure, these ‘as-made’ polyketones were found to show multiple melting behaviour on heating.
