Aim To obtain poly(phthalazinone ether ketone)s (PPEKs) with good solubility and excellent thermal stability. Methods Through the molecular design, the alkyl side groups was introduced into the backbone of PPEKs. Results A series of novel PPEKs containing alkyl pendants was synthesized by aromatic nucleophilic displacement polycondensation. These PPEKs were fully soluble in various polar aprotic solvents such as NMP, DMAc, DMF, pyridine, and chloroform at room temperature. The temperatures of 10 ％ weight loss ( T d10) in N2 of the PPEKs were above 454 ℃ and the glass transition temperatures (Tgs) ranged from 208 ℃ to 236 ℃. Conclusion The method may be used to the high performance engineer plastic in the future.
