| Abstract: | thylene-propylene block copolymers taken from different batches were charcterized by means of 13C-NMR, X-ray, DSC, DMA, etc. It is found that their molecular chains consist mainly of ethylene and propylene with a small number of other sequencestructures. The different distributions of the sequence structures in samples exhibit different physical properties. and based on this is the study on the relationship between structures and properties. |

| Keywords: | ethylene-propylene block copolymer sequence composition of chain segment sequence distribution mechanical property |
