Synthesis and characterization of novel organosoluble methyl substituted poly(aryl ether ketone)s containing sulfone linkage

Several new methyl substituted poly(aryl ether ketone)s containing sulfone linkage with inherent viscosities of 0.62-0.84 dL/g have been prepared from 4,4 -bis(2-methylphenoxy)diphenylsulfone and 4,4 -bis(3-methylphenoxy) diphenylsulfone with terephthaloyl chloride and isophthaloyl chloride by electrophilic Friedel- Crafts acylation in the presence of DMF with an hydrous AlCl3 as a catalyst in 1,2-dichloroethane, respectively. These polymers having weight-average molecular weight in the range of 71,000-49,000 are all amorphous and show high glass transition termperatures ranging from 167°C to 191°C, excellent thermal stability at temperatures over 400°C in air or nitrogen, high char yields of 51-58% in nitrogen and good solubility in CHCl3 and polar solvents such as DMF, DMSO and NMP at room temperature.
