Abstract
Provided is a composition for interfacially polymerizing polyamide including an amine compound and a chain-type-structured additive containing one or more amino groups and two or more hydroxyl groups, and a method for manufacturing a water treatment separation membrane, and a water treatment separation membrane using the same.
Claims6
An aqueous solution composition for interfacially polymerizing polyamide, comprising:
- an amine compound in an amount from 0.001 wt % to 10 wt % based on 100 wt % of the composition;
- a chain-type-structured additive containing one or more amino groups and two or more hydroxyl groups each separately bonded to a carbon atom in an amount from 0.01 wt % to 1 wt % based on 100 wt % of the composition;
- a surfactant in an amount from 0.005 wt % to 0.5 wt % based on 100 wt % of the composition;
- and
- water.
