摘要: 采用熔融共混方法制备了聚醚醚酮和聚醚醚酮酮的共混物,用DSC对共混物的熔融行为和等温结晶行为进行了研究.结果表明,共混物熔点随聚醚醚酮含量增加而降低,但与聚醚醚酮酮有相同的平衡熔点,二者共混没有改变其结晶的成核与生长机制.

关键词: 聚醚醚酮, 聚醚醚酮酮, 共混物, 熔融行为, 等温结晶行为

Abstract: Blends of poly(ether ether ketone ketone)(PEEKK) with poly(ether ether ketone)(PEEK) were prepared by melting mixing. The thermal and crystallization behaviors were characterized by DSC. The Avrami exponent is almost independent on composition and crystallization temperature, but the crystallization rate constant decreases as PEEKis in major phase. The melting point of blends decreases with increasing PEEKcontent but the equilibrium melting point is not affected by composition.

Key words: Poly(ether ether ketone), Poly(ether ether ketone ketone), Blend, Melting behavior, Isothermal crystallization behavior
