(57) [Problem] To provide a propylene-based polymer having an excellent balance of melt strength, elongation characteristics and fluidity, and a foamed molded product thereof. SOLUTION: In a first step, a monomer mainly containing propylene is polymerized to produce a crystalline propylene polymer component (A) having an intrinsic viscosity of 5 dl / g or more. A propylene-based polymer obtained by continuously producing a crystalline propylene-based polymer component (B) having an intrinsic viscosity of less than 3 dl / g by polymerizing a monomer to be used, and a component in the propylene-based polymer The proportion of (A) is 0.05% by weight or more and less than 25% by weight, the intrinsic viscosity of the whole propylene-based polymer is less than 3 dl / g, Mw / M A propylene-based polymer, wherein n is less than 10, and a foam molded article obtained therefrom. |
