| titleOfInvention | Method for producing propylene polymer |
| abstract | Provided is a method for producing a propylene polymer capable of easily and sufficiently reducing a catalyst residue in the propylene polymer. The method for producing a propylene polymer includes the following step (1) and step (2). Step (1) is a step of polymerizing propylene in the presence of a catalyst to obtain a propylene polymer. Step (2) is a step of washing the propylene polymer obtained in step (1) with a deashing agent to remove the catalyst residue in the propylene polymer, the step satisfying the following formula (1). (1): 4.4 × log(T) - log(EW) > 0.34 × (δ(W) - δ(E)) (In the formula, T represents a temperature (°C) when the propylene polymer is washed with a deashing agent. EW represents a water content (% by weight) in the deashing agent. δ(W) represents a Hansen solubility parameter of water. δ(E) represents a Hansen solubility parameter of the deashing agent.) |
