中文摘要	in this work, two industrial bimodal high density polyethylene resins, resin a and resin b having similar molecular weight (m-w), molecular weight distribution (m-wd), and short-chain branching (scb) content but different mechanical properties, were fractionated through cross-fractionation. the fractions were further, characterized by gpc, c-13 nmr, dsc and ft ir techniques. these two resins were firstly fractionated into two franctions, i.e. high-temperature and low temperature fractions, via preparative solution crystallization fractionation. resin a with much better mechanical properties contains more high-temperature fractions with longer crystalizable sequences. the scb content in the low temperature fraction of resin a is lower than the of resin b. both low-temperature fractions were then further fractionated using solvent gradient fractionation (sgf). the characterization of sgf fraction indicates that most of the branches fall into the high molecular weight chain in both low-temperature fractions.
