Title:
HYDROPHILIC MEMBRANE AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JPH04227824
Kind Code:
A
Abstract:
PURPOSE: To produce a hydrophilic membrane which reduces pollutants on its surface and is excellent in resistance to chemicals and water permeability.
CONSTITUTION: A membrane for membrane filtration comprising a polymer matrix formed by coagulation with a liquid coagulant from a casting syrup is produced. The polymer matrix is linked to a hydrophilic group of a compound which has a hydrophilic chain moiety. The above compound is coupled on either side to a hydrophobic chain and is anchored in the polymer matrix by non- chemical bonding, and is a compound which has a molecular weight of at least 2000 and can be used as a thickening agent.
