Document Type and Number:
Japanese Patent JP2015077595
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method to fractionate a polyisocyanate mixture in a liquid phase using a selective permeation film.SOLUTION: A method of this invention fractionates a polyisocyanate mixture in a liquid phase under existence of suitable one solvent or mixture of multiple solvents as required, through a selective permeation film into a permeation flow and a retention flow having mutually different polyisocyanate compositions, which are also different from an original mixture. The method to fractionate a polyisocyanate mixture uses the selective permeation film comprising: a polyimide-based or polydivinyl fluoride-based polymer film, a pretreated ceramic film; or an inorganic film.
