摘　　要：DDV、DSC、WAXD、萃取和Raman光谱实验表明,在所有组成下,LDPE/EPO共混体系共晶相容.WAXD法测定表明,LDPE/EPO共混体系的结晶度随EPO组分含量的增加而降低,EPO未能进入LDPE晶胞中.The miscibility and the crystal structure of LDPE EPO blends have been investigated by DDV, DSC, WAXD, Laser Raman spectroscopy and extraction separation. It indicates that LDPE/EPO are of good cocrystallization and miscible blend system at all the compositions. The degress of crystallinity and crystallite sizes of LDPE/EPO blends decrease with increasing content of EPO and the unit cell parameters are independent of the blend compositions.
