| 中文摘要 | two commercial biaxially oriented polypropylene (bopp) resins, resin a and resin b, having different processing properties, were fractionated by preparative temperature-rising elution fractionation (tref). the tref fractions were further characterized by gel permeation chromatography (gpc), gel permeation chromatography coupled with light scattering (gpc-ls), wide-angle x-ray diffraction (waxd), and differential scanning calorimetry (dsc). gpc-ls did not find visible long-chain branching in either resin a or b. the results from tref and dsc indicate that the fractional melting parameter f(t) may be used to predict the profile of the tref cumulative weight distribution curve. gpc results show that the molecular weights of the fractions tend to increase with elution temperature. waxd and dsc data show that the crystallinity of fractions does not increase monotonically with increase of elution temperature. there appears to be a maximum in the plot of crystallinity versus elution temperature. the high-speed bopp resin a has a lower isotacticity but a homogeneous isotacticity distribution and a higher molecular weight but a broader molecular weight distribution than resin b. |
