Abstract A thin film composite polyamide membrane having a porous support and a thin film polyamide layer comprising a reaction product of m-phenylene diamine (mPD) and trimesoyl chloride (TMC), characterized by the thin film polyamide layer having a critical strain value of less than 10%. In another embodiment, the thin film polyamide layer has a modulus of greater than 0.75 (GPa). In yet another embodiment, the thin film polyamide layer has an equilibrium swelling value of at least 45%. In another embodiment, the thin film polyamide layer has a thickness of at least 230 nm.
