PROBLEM TO BE SOLVED: To provide a propylenic polymer having a melt strength, an elongation characteristic and a flowing property in an excellent balance, and to provide a foamed molded product. SOLUTION: This propylenic polymer comprises a propylenic polymer obtained by continuously producing (A) a crystalline propylenic polymer component and (B) a crystalline propylenic polymer component. Therein, the amount of the component A in the propylenic polymer is 0.05-25 wt.%, and the whole propylene polymer has an intrinsic viscosity of <3 dl/g and a Mw/Mn ratio of <10. The crystalline propylenic polymer component A is obtained by polymerizing monomers containing propylene as a main component in the first stage and has an intrinsic viscosity of >=5 dl/g. The crystalline propylenic polymer component B is obtained by polymerizing monomers containing propylene as a main component in the second and subsequent stages and has an intrinsic viscosity of <3 dl/g. The foamed molded product is obtained from the propylenic polymer. |
