Title:
α−オレフィン低重合体の製造方法
Document Type and Number:
Japanese Patent JP6711029
Kind Code:
B2
Abstract:
An object of the present invention is to provide a method for suppressing the precipitation of polymers with a high concentration dissolved in a solvent in the operation termination step and suppressing the blockage of the apparatus by the polymers even when the polymers with a high concentration are precipitated, and the invention relates to a method for producing an α-olefin low polymer comprising a production operation step and an operation termination step, wherein the supply position of a supply liquid to a distillation column in the operation termination step is changed to a position lower than the supply position of a supply liquid to the distillation column in the production operation step.
