摘要：

New activated phthalide-containing dihalogeno derivatives were synthesized, and cardo polyarylene ether ketones based on them were prepared. The effect of the type of the halogen atom (fluorine, chlorine, or bromine) on the efficiency of polycondensation was estimated. It was demonstrated that high-molecular-weight cardo polyarylene ether ketones can be obtained only from the difluoro derivative. The synthesized polymers are amorphous compounds characterized by high glass transition temperatures (210-250 degrees C). These polymers are soluble in many organic solvents and form strong transparent films.
