| Abstract: | Several propylene copolymers with high impact and high flowability were characterized using nuclear magnetic resonance,dynamic mechanical analysis,differential scanning calorimeter,and rheological properties.Sample 1# had higher ethylene content,higher isotacticity and lower xylene solubility,the homopolymer and copolymer phases showed good compatibility,and provided the best comprehensive mechanical properties.Sample 3# had higher content of PE nodes and ethylene,so it possessed the highest impact strength... |
