| titleOfInvention | Propylene block copolymer, production method and use thereof |
| abstract | (57) [Summary]nPROBLEM TO BE SOLVED: To provide excellent rigidity and impact resistance, and particularly Excellent in injection moldability with outstanding flow marks and spots A process that enables the production of injection-molded products with an excellent appearance. Ropylene block copolymer, its production method and use provide.nSOLUTION: (1) 2 to 36 parts by weight of decane-soluble component at 64 ° C. %, (2) Is the 64 ° C decane soluble component ethylene? Containing units derived from 20 to 55 mol%, (3) Frequency dependence of the decane-soluble component at 64 ° C at 200 ° C In viscoelasticity measurement, the angular velocity was measured at ω 0.01 rad / s. Viscosity η * (ω 0.01 ) And at an angular velocity of ω100 rad / s Measured viscosity η * (ω 100 ) Ratio η * (ω 0.01 ) / η * (ω 100 ) Is 50 or more Polymer. (i) high molecular weight rubber component, (ii) crystalline polypropylene The len component and (iii) the low molecular weight rubber component are sequentially produced, and To produce a propylene block copolymer. |
