Abstract
High molecular weight m-substituted poly(ether ketone-ketone) has been synthesized by electrophilic precipitation polycondensation via two d ifferent ways: reaction of isophthaloyl chloride with diphenyl ether a nd reaction of isophthaloyl chloride with 1,3-bis(4-phenoxybenzoyl)ben zene. The second way of synthesis was found to give structurally more perfect polymers with higher molecular weights. In both cases polycond ensation proceeded with precipitation of the polymers formed as unifor m particles. The influence of reaction conditions has been studied. Mo nomer concentration and monomer stoichiometric ratio were shown to aff ect the polymer properties.
