“…Copolymerization with a suitable monomer is an effectively method to control the swelling level of membranes, i.e., by tuning the ratio of the hydrophilic monomer content in the polymer's backbone [84]. However, the AMPS monomer is immiscible with most of the monomer oils and thus its use has seldom been reported.…”

Abstract:The relentless increase in the demand for useable power from energy-hungry economies continues to drive energy-material related research. Fuel cells, as a future potential power source that provide clean-at-the-point-of-use power offer many advantages such as high efficiency, high energy density, quiet operation, and environmental friendliness. Critical to the operation of the fuel cell is the proton exchange membrane (polymer electrolyte membrane) responsible for internal proton transport from the anode to the cathode. PEMs have the following requirements: high protonic conductivity, low electronic conductivity, impermeability to fuel gas or liquid, good mechanical toughness in both the dry and hydrated states, and high oxidative and hydrolytic stability in the actual fuel cell environment. Water soluble polymers represent an immensely diverse class of polymers. In this comprehensive review the initial focus is on those members of this group that have attracted publication interest, principally: chitosan, poly (ethylene glycol), poly (vinyl alcohol), poly (vinylpyrrolidone), poly (2-acrylamido-2-methyl-1-propanesulfonic acid) and poly (styrene sulfonic acid). The paper then considers in detail the relationship of structure to functionality in the context of polymer blends and polymer based networks together with the effects of membrane crosslinking on IPN and semi IPN architectures. This is followed by a review of pore-filling and other impregnation approaches. Throughout the paper detailed numerical results are given for comparison to today's state-of-the-art Nafion ® based materials.

“…These properties can be usually obtained by incorporation of functional groups in the polymer chains. Extensive work has been reported for the synthesis of functionalized nanogels based on copolymerization of AM/NIPAM with carboxylic/sulfonic acid containing monomer by plasma-initiated, solution or dispersion polymerization (19)(20)(21). The recent progress in the field is towards the synthesis of copolymer microgels based on sulfonic acid-acrylamide by microemulsion polymerization (22)(23)(24).…”

Poly(acrylamide-co-2-acrylamido-2-methyl-1-propanesulfonic acid) poly(AM-co-AMPSA) nanogels were prepared through inverse microemulsion polymerization with low AMPSA/AM weight ratio in the feed (up to 0.3357) to control particle size and pH sensitivity. An aqueous solution of AM and AMPSA was used as the dispersed phase for microemulsion with sodium bis(2-ethylhexyl) sulfosuccinate (AOT)/Toluene solution as the dispersion medium. The polymerization was carried out at 50 • C in the presence of 2,2-azobisisobutyronitrile (AIBN) and N,N -methylenebisacrylamide (NMBA) as an initiator and a crosslinker, respectively. Fourier transform infra red spectrophotometer (FTIR) and 1 H-nuclear magnetic resonance spectroscopy ( 1 H-NMR) studies confirm the occurrence of copolymerization between the two monomers. The hydrodynamic diameter of synthesized poly(AM-co-AMPSA) nanogels is found to be in the range of 63-125nm as measured by dynamic light scattering (DLS). The equilibrium swelling and the effect of pH on particle size of copolymer nanogel are found to depend on the copolymer composition. The polymer chain composition, thermal properties and morphology of nanogels were measured by elemental analysis, thermogravimetric analyzer (TGA) and differential scanning calorimeter (DSC), and scanning electron microscope (SEM), respectively.

“…2‐Acrylamido‐2‐methylpropanesulfonic acid (AMPS) has previously been copolymerized with a range of different AM monomers 6, 7. A series of random and graft copolymers of AM with NaAMPS, diacetone AM, and sodium acrylate has been studied 8.…”

A series of graft copolymers poly(acrylamide‐co‐2‐acrylamido‐2‐methylpropanesulfonic acid) [Ap‐g‐p(AM‐co‐AMPS)] have been synthesized by graft copolymerization of amylopectin (Ap) with acrylamide (AM) and 2‐acrylamido‐2‐methylpropanesulfonic acid (AMPS). The copolymerization has been carried out by solution polymerization technique and using ceric ammonium nitrate (CAN) as initiator. The characterization of graft copolymer has been carried out by elemental analysis fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (NMR), and scanning electron microscopy (SEM). The effects of reaction conditions on graft copolymerization and the use of the copolymer as flocculating agent in kaolin suspension have been investigated. Experiments have shown that graft copolymer with higher grafting level, higher intrinsic viscosity, and higher anionic degree can be obtained by changing the method of addition of monomers and by controlling the ratio of AMPS and AM. The flocculation performances have been investigated through jar test method, and it has been observed that the graft copolymer with molar ratio of 2 : 1 of AM and AMPS shows best performance in flocculating kaolin suspension. Metal ion sorption study with Cu2+ has shown that the graft copolymer absorbs Cu2+ efficiently. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
