Title:
重合粉体の流動性改良方法
Document Type and Number:
Japanese Patent JP4275497
Kind Code:
B2
Abstract:
To provide a method for improving fluidity of polymer powder, with which fluidity of polymer powder such as polyolefin powder, etc., in an environment field of powder flow is improved, a heat spot hardly occurs in polymerization, excellent fluidity is secured even in dead spaces in piping and various facilities in which polymer powder is moved and neither a polymer lump nor a sheetlike material is formed.
The method for improving fluidity of polymer powder comprises supplying a specific fluidity improver to the environment field of powder flow in a monomer polymerization process or a storage process of the obtained polymer powder.
