Abstract A porous molecular imprinted latex membrane (MILM) with L-Tryptophan as template molecule, adipic acid dihydrazide (ADH) as cross-linker and glucose as porogen was prepared at ambient temperature from polyacrylate core-shell emulsion incorporated with diacetone acrylamide (DAAM) and acrylic acid (AA). The strength of interaction of functional monomers with L-Tryptophan was compared. The effects of functional monomers on the separation properties of MILM were investigated. The results show that the MILM with developed void structures can be obtained by the method proposed in this paper. The strength of interaction between the three functional monomers and L-Tryptophan is in the following order: L-Trp/ADH>L-Trp/DAAM>L-Trp/AA. ADH, AA and DAAM have considerable influence on crosslinking degree and consequently the permeation properties of MILM. Compared with non-imprinted membrane, the acquired MILM exhibits selective recognition behavior towards template with separation factor reaching over 2.0.
