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