| titleOfInvention | Propylene-based block copolymer particles |
| abstract | Propylene-based block copolymer particles in accordance with the present invention are obtained by copolymerizing ethylene and propylene to form an ethylene-propylene copolymer in the presence of propylene polymer particles. The ratio of the intrinsic viscosity eta[A] of a 20 DEG C. xylene-soluble component of the copolymer particles to the intrinsic viscosity eta[B] of a 20 DEG C. xylene-insoluble component of the copolymer particles, eta[A]/eta[B], is 2.9 to 7.5. The content of the ethylene-propylene copolymer is 5 to 50 wt. % on the basis of the total weight of the block copolymer particles. The ethylene content of the ethylene-propylene copolymer is 20 to 55 wt. % on the basis of the weight of the ethylene-propylene copolymer. The standard deviation of the ethylene contents of the individual block copolymer particles is less than 7. |
