对聚氧化乙烯/聚酚氧(PEO/PH)共混体系的研究表明,随共混体系中非晶组份PH含量的增加,Avrami指数n值由2.0～2.3变为1.5～2.0,体系的结晶由盘状生长转化为纤维状生长;成核方式由方式Ⅰ转化为方式Ⅱ.PEO/PH共混体系的平衡熔点随PH含量的增加而降低,相互作用能量密度B=-1.46cal/mol,说明体系是互容的。
The results of poly (ethylene oxide) / polyphenylene oxide (PEO / PH) blends show that the Avrami index n changes from 2.0 to 2.3 to 1.5 to 2.0 with the increase of the content of amorphous component (PH) in the blends. Crystallization from disk growth to fibrous growth; nucleation mode from mode Ⅰ to mode Ⅱ .PEO / PH blend system equilibrium melting point decreases with increasing PH content, the interaction energy density B = -1.46cal / mol , Indicating that the system is mutual tolerance.
