摘要： 由亲核缩聚反应合成了酚酞(PPh)-二氯二苯酮(DCBP)-对苯二酚(HQ)三元共聚物并对结构和性能作了初步鉴定。随PPh/HQ组成的不同可得到结晶或无定形聚芳醚酮。聚合物的玻璃化转变温度在143～228℃之间,且随pph含量而异。三元共聚物较酚酞聚芳醚酮(PEK-C)均聚物有更好的耐溶剂性及热稳定性。

Abstract: Polyaryletherketone copolymers of high molecular weight have been synthesized bypolycondensation of phenolphthalein(PPh), hydroquinone (HQ) and 4,4'-dichlorobenzophenone(DCBP) using K2CO3 as a catalyst and sulfolane as solvent.Both amorphous and crystallinecopolymers can be made depending on the molar ratio of PPh to HQ.The copolymers have preliminarily been characterized by IR, DSC and WAXD techniques.Tg of the copolymers were between 143℃(Tg of pure HQ-PEK) and 228℃(Tg of pure PPh-PEK), attd they incrsase monotonically as a function of PPh content in the copolymers.The copolymers increase have better solvent and heat resistance prorerties than pure PPh-PEK (PEK-C).

Key words: phenolphthalein, polyaryletherketone, copolymer, synthesis
