  • Patent number: 8618244
    Abstract: Disclosed herein are a method for preparing a benzoxazole-based polymer by thermal rearrangement, the benzoxazole-based polymer prepared by the method and a gas separation membrane comprising the polymer. More specifically, provided are a method for preparing a benzoxazole-based polymer by subjecting poly(hydroxyamide) as an intermediate to thermal treatment involving dehydration, the benzoxazole-based polymer obtained thereby and gas separation membrane comprising the polymer. The benzoxazole-based polymer of the present invention can be simply prepared by thermally rearrangement via thermal treatment at low temperatures, and thus exhibits superior mechanical and morphological properties and has well-connected microcavities. Due to showing excellent permeability and selectivity for various gases, the benzoxazole-based polymer is suited for application to gas separation membranes, in particular, gas separation membranes for small gases.

  • Publication number: 20130337263
    Abstract: A fine polymer particle production method includes producing an emulsion in a liquid prepared by dissolving and mixing a polymer A and a polymer B in organic solvents in which a solution phase composed primarily of the polymer A and a solution phase composed primarily of the polymer B are formed as separate phases, and bringing it into contact with a poor solvent for the polymer A to precipitate the polymer A. This method serves for easy synthesis of fine polymer particles with a narrow particle size distribution and the method can be effectively applied to production of highly heat-resistant polymers that have been difficult to produce with the conventional methods.

  • Publication number: 20130289204
    Abstract: It is possible to provide polyimide powder which has an average size of 25 ?m or less and is free from metal impurities which would otherwise be produced due to abrasion of a machine used for mechanical milling. The polyimide powder is an aggregate of fine particles produced through precipitation of polyimide dissolved in a treatment solution containing a basic substance. A residual amount of alkali metal derived from the basic substance contained in the treatment solution is 1% or less of a total amount of the polyimide powder. It is possible to reduce bad effects due to an alkali metal residue and to prevent decomposition of polyimide by the alkali metal residue.
