Abstract: Using FTIR,13C NMR etc.,we obtain the information of chain structure in composition and sequences distribution of high impact polypropylene.With DSC,WAXD etc.,we also study their crystalline behavior,transition of molten polymers and crystal structure.By various methods,we effectively characterize the sequences structure of high unimpact polypropylene.

Key words: High impact polypropylenes, Distribution of sequences, Ethylene block
