(A) (A) Isopropylene triad fraction of 98% or more as measured by 13 C-NMR of a propylene unit chain portion comprising a head-tail bond, (B) 13 C-NMR 2,1 of propylene monomer in total propylene insertion The proportion of the positionally irregular units based on the insertion is 0.03% or less, the proportion of the positionally irregular units based on the 1,3-insertion of the propylene monomer is 0.06% or more, and (C) the weight average molecular weight is 10,000 to 1,000,000, (D) melting point is 1 A propylene polymer having a temperature of 60 ° C. or higher. [Effect] A propylene-based polymer having high transparency and high impact strength is provided despite excellent rigidity, heat resistance, moldability, and gloss. |
