| 中文摘要 | the purpose of the present work is to investigate the compositional difference of polypropylene-polyethylene block copolymers (pp-b-pe) manufactured industrially by the process of degradation and hydrogenation, respectively. each of the pp-b-pe copolymers was fractionated into three fractions with heptane and chloroform. the compositions of the three fractions were characterized by c-13 nuclear magnetic resonance (nmr) and fourier transform infrared (ftir) spectroscopy, as well as differential scanning calorimetry (dsc) and thermal fractionation. the results showed that the chloroform-soluble fraction was amorphous ethylene-propylene rubber, and the content of the rubber in pp-b-pe manufactured by hydrogenation was less than that by degradation. the degree of crystallinity of the chloroform-insoluble fraction of the pp-b-pe manufactured by hydrogenation is higher than that of by degradation. |
