ABSTRACT = {The effect of the ether/keto ratios on the thermal properties, mechanical performances and
crystallization behavior of the Poly(aryl ether ketone)s (PAEK) were investigated. A formula was
proposed the estimate the melting temperatures of the PAEKs with high accuracy. Glass transition
temperatures were affected by the ether/keto ratios and molecular weights, and were related
with the brittle-tough transition of the PAEKs. Mechanical performances of tensile, impact,
flexural and compressive strength decreased with the increase of ether/keto ratios, while elongation
had a trend of increase. The non-isothermal crystallization curves exhibited well linearity when
treated with Jeziorny’s model, and two crystallization processes were found. The activation
energies of the PAEKs were calculated to be 550~580 KJ/mol by Doyle’s method. All the
PAEKs exhibited spherulites and their sizes decreased with the increase of ether/keto ratios.},
