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.
