A composite semipermeable membrane which comprises a porous substrate and an ultrathin dense layer having solute removal performance formed on said substrate by polymerization by crosslinking of a reactive material composed of at least one material selected from the group consisting of
(a) a mixture of triazine represented by the general formula:
(wherein R', R2, R3, R' and R5 each represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms), and polyamine monomer,
(b) said triazine modified with amine,
(c) a mixture of said triazine modified with amine, and polyamine monomer,
(d) an oligomer composed of said triazine and polyamine monomer, and
(e) a mixture of an oligomer composed of said triazine and polyamine monomer, and polyamine monomer,
as a main component, with a polyfunctional crosslinking reagent having two or more functional groups capable of reacting with amino groups in the molecule, and a process for preparing the same.
