| titleOfInvention | Crystalline polypropylene |
| abstract | (57) [Abstract] [Purpose] The flexural modulus and heat deformation temperature are high, rigidity and heat resistance are improved, and also the moldability and impact resistance are excellent, and the rigidity is high, so thinning can be achieved. , Can be made lighter, Provided is a crystalline polypropylene which is effective from the viewpoint of resource saving and productivity, and by improving rigidity and heat resistance, which can be used as a substitute for the use of polystyrene and ABS resin. [Summary] The density [d], the frequency ω 0 and the elastic modulus G 0 obtained from the dynamic melt viscoelasticity measurement are [d] ≧ 0.9091 + 1.103 × 10 −3 logω A crystalline polypropylene satisfying the relationship of 0 −7.686 × 10 −4 log G 0 , and the same crystalline polypropylene obtained by using a specific magnesium chloride-supported stereoregular polymerization catalyst. |
