摘要:
A fluoroalkene is reacted with hydrogen iodide gas in the presence of a catalyst to produce a fluoroalkyl iodide represented by the general formula (II): Rf-CH2CH2I (II) wherein Rf represents C1-20 perfluoroalkyl or polyfluoroalkyl. The fluoroalkyl iodide is reacted with a carboxylic acid salt to produce a fluorinated ester.
摘要:
The invention provides a hydrophilizing agent which is to be added to a polymer having a large contact angle to produce a porous polymer film that has a small contact angle and that can maintain this small contact angle even after 168-hour contact with an aqueous sodium hypochlorite solution. The hydrophilizing agent contains a fluoropolymer having a contact angle of 50° or smaller and a weight reduction rate of 7% or lower.
摘要:
The present invention aims to provide a porous polymer membrane that is excellent not only in water permeability and alkali resistance but also in mechanical strength. The porous polymer membrane of the present invention includes a fluoropolymer (A) that includes a vinylidene fluoride unit and a tetrafluoroethylene unit.
