<p>Provided is a composite semipermeable membrane comprising a microporous support membrane and a separation functional layer formed thereon, wherein the separation functional layer is formed from Compound (A) in which a reactive group(s) having an ethylenically unsaturated group and a hydrolyzable group(s) are bonded directly to a silicon atom, Compound (B) having an ethylenically unsaturated group, the Compound (B) being different from said Compound (A), and Compound (C) having an ethylenically unsaturated group, the Compound (C) being different from said Compound (A) and (B), by condensation of hydrolyzable groups that the Compound (A) has and polymerization of ethylenically unsaturated groups that the Compound (A), the Compound (B), and the Compound (C) have, and the Compound (A), the Compound (B), and the Compound (C) satisfy the relationship of the following equation (I): Q A - Q C + Q B - Q C = Q A - Q B
(Qx represents an Alfrey-Price Q value of Compound X). A composite semipermeable membrane having excellent chemical resistivity to chemicals represented by chlorine, separation performance, and water permeability can be provided.</p> |
