The present invention relates to a porous membrane suitable for use in high pressure filtration method.

An ultra-thin film of a thermosetting resin, such as a phenolic resin, can be produced by a method that includes introducing a solution containing an aldehyde-based compound and a compound (A) capable of undergoing addition condensation with an aldehyde-based compound into an electrochemical cell, which includes a working electrode and a counter electrode, and applying a positive potential to the working electrode to form a thin film on the working electrode.

Described herein are anionic phenylene oligomers and polymers, and devices including these materials. The oligomers and polymers can be prepared in a convenient and well-controlled manner, and can be used in cation exchange membranes. Also described is the controlled synthesis of anionic phenylene monomers and their use in synthesizing anionic oligomers and polymers, with precise control of the position and number of anionic groups.

The present disclosure is directed to microporous ladder polymers containing amine-functionalized monomer segments, amidoxime-functionalized monomer segments, or a combination thereof. Monomer compounds for preparation of the polymers are also described, as well as membranes and electrochemical cells containing the polymers. ##STR00001## ##STR00002##

An ultra-thin anion exchange membrane incorporates functional additives to provide improved water management. Without the functional additives the ultra-thin membrane may have high cross-over and not be effective for many applications. A composite anion exchange membrane includes a porous scaffold support such as a porous polymer. The anion exchange polymer may be coupled to the porous scaffold, such as by being imbibed into the pores of the porous scaffold. The functional additives may contribute to increase water production, water retention, back-diffusion and reduce the gas crossover. A functional additive may include a reactive species, including a catalyst that reacts with oxygen or hydrogen, a plasticizer, a hygroscopic material and/or a radical scavenger.
