Abstract: Apolyolefin alloy sample was fractionated by using temperature rising elution fractionation(TREF) technique.From the TREFcurve it was found that this sample was composed of three components,Some fractions were characterized by 13C NMRand DSC.The results show that these three components are ethylene-propylene random copolymer,ethylene-propylene block copolymer and propylene homopolymer.

Key words: Temperature rising elution fractionation, Polyolefin, Blends
