摘要
利用合成的新型单体,采用亲核取代法制备了5类聚芳醚酮.用DSC和WAXD对聚合物的研究表明:新型聚芳醚酮与聚醚醚酮的结晶结构相同,其熔点及玻璃化转变温度均随聚合物结构单元中酮基含量的增加而升高.
The New aromatic polyarylether ketone is synthesized by new monomers, the general properties are studied by IR, DSC, WAXD. The results indicate that the new aromatic polyaryl ether ketones have the same crystal structure as PEEK. The glass transition point and the melting temperature get higher with the increasing of the ketone content of polyarylether ketone
