X-ray diffraction line profiles of low density polyethylene(LDPE)/(ethylene-propylene-octene-1)copolymer(EPO) blends have been analyzed with variance range function method.Theories for determining the microparacrystallite size and the distortion parameter from single reflection have been described,and the value of these two parameters at(110)and(200)directions have been determined.
