| titleOfInvention | Crystalline polypropylene |
| abstract | (57) [Abstract] [Purpose] Flexural modulus, heat distortion temperature is higher, rigidity, It has improved heat resistance, as well as excellent moldability and impact resistance. Therefore, it is possible to reduce the wall thickness and weight, it is effective in terms of resource saving and productivity, and rigidity and heat resistance. By providing improved crystalline polypropylene, a crystalline polypropylene that can be used as a substitute for the use of polystyrene, ABS resin and the like is provided. [Structure] Storage elastic modulus G'in dynamic melt viscoelasticity measurement And the elastic modulus at which the loss elastic modulus G ″ coincides with ω 0 and the elastic modulus at that time is G 0 , an IPF between these and the isotactic pentad fraction in the 13 C-NMR measurement: IPF ≧ 1.65 log ω 0 −1.15 log G 0 +9 9.3 Crystalline polypropylene satisfying the relationship of 9.3, and the same crystalline polypropylene obtained by using a specific stereoregular polymerization catalyst. |
