摘要

Abstract

A new copoly(ether ketone ketone)(NPEKK)has been synthesized from 4

5-bis(4-fluorobenzoyl)-l-methylcyclohexene

4-(4-hydroxyphenyl)-2

3-phthalazin-l-one and 2

2-p-hydroxyphenyl一iso-propane via nucleo-philic polycondensation reaction．The ring-closing reaction of NPEKK with hydrazine gives the cyclizing product CNPEKK．The new polymers have been studied with FT-IR．DSC and TGA．It has been proved that the synthesized poly(ether ketone ketone)s is very soluble in many organic solvents

thermal stable and have good tensile properties．While

CNPEKK is more stable

but less soluble．
