titleOfInvention | Polypropylene-based resins and polypropylene-based resin compositions |
abstract | A polypropylene-based resin has melt index of 30-70 g/10 minutes and 25[deg]C xylene-soluble content of 5-15 wt.%. The 25[deg]C xylene-soluble component has ethylene unit content of 20-30 wt.%, and intrinsic viscosity (eta ) of not less than 2 dl/g. The resin has 25[deg]C xylene-insoluble component having melt index of 40-130 g/10 minutes, and stereospecificity index of not less than 98.5%. A polypropylene-based resin has melt index of 30-70 g/10 minutes and 25[deg]C xylene-soluble content (x) of 5-15 wt.%. The 25[deg]C xylene-soluble component has ethylene unit content (z) of 20-30 wt.%, and intrinsic viscosity (eta ) of not less than 2.00 dl/g in decalin at 135[deg]C. The ethylene unit content (z) is obtained by isotopic carbon nuclear magnetic resonance spectrometry ( 1> 3>C-NMR). The resin has 25[deg]C xylene-insoluble component having ethylene unit content (y) wt.%, as obtained through isotopic carbon nuclear magnetic resonance spectrometry ( 1> 3>C-NMR), satisfying the relational formula: 100y/[yX(1-x/100)+x]=1.13z-16.6. The 25[deg]C xylene-insoluble component has not less than 2 wt.% of the content of its constituent component having a molecular weight of not less than 10 6>, in its molecular weight distribution curve as obtained through gel permeation chromatography (GPC), based on polystyrene. The xylene-insoluble component has melt index of 40-130 g/10 minutes, and stereospecificity index of not less than 98.5%, as obtained through isotopic carbon nuclear magnetic resonance spectrometry ( 1> 3>C-NMR). An independent claim is also included for polypropylene-based resin composition comprising: (a) polypropylene-based resin (45-90 wt.%); (b) copolymer comprising one or more units chosen from ethylene and alpha -olefins having 3 or more carbon atoms (5-50 wt.%); and (c) talc (0-25 wt.%). |
