Title:
MOLDED ARTICLE OF FLUORINE RESIN
Document Type and Number:
Japanese Patent JPH03140353
Kind Code:
A
Abstract:
PURPOSE:To obtain a molded article of fluorine resin useful in fields of water treatment or purification of drug, etc., having excellent heat resistance, chemical resistance, shape-enduing property, ion-exchange property, adsorbing property and separating property comprising fluorine resin having aromatic compound in side chain through ether bonding. CONSTITUTION:(A) At least one compound expressed by formula I to formula V (Rf is fluoroalkyl group) and vinyl-based fluorine resin containing CH2 (preferably polyvinylidene fluoride, etc.) are molded to any shape (preferably porous membrane) from molten or solution state and subjected to reaction treatment in the presence of aromatic alkyl alcohol and basic compound to afford a molded article of fluorine resin having aromatic compound in side chain through ether bonding. Otherwise, (B) cation-exchange group (e.g., sulfonic acid group), anion-exchange group, chelateexchange group or crown ether group is further introduced into aromatic compound in the side chain of the composition A to afford the second aimed molded article of fluorine resin.
