摘要： A propylene polymerization reaction apparatus and a production method of a propylene-based polymer are capable of producing a continuous multi-stage polymer in low cost, high productivity and stably, and significantly reducing generation amount of an off-specification product accompanying change of polymerization condition, in multi-stage continuous vapor phase polymerization method of a propylene-based polymer using a catalyst for olefin polymerization. A reaction apparatus for producing a propylene-based polymer by a multi-stage continuous vapor phase polymerization method is used. One or more reactor of a horizontal-type reactor having inside a stirring machine which rotates around a horizontal axis, and a continuous stirred tank reactor to be connected to the horizontal-type reactor are provided, and a production method of a propylene-based polymer using the same.

摘要： A concentration distribution of a rubber component in block copolymer particles is computed based on the operating conditions of a polymerization apparatus, a growth model equation of polymer particles on a solid catalyst component, and a residence time distribution of the particles in each of a homopolymerization stage and a copolymerization stage, and the gel content of the block copolymer is estimated based on the computation. The gel content of a propylene block copolymer can thereby be estimated precisely.
