Synthesis and Characterization of Poly[((maleic anhydride)‐alt‐styrene)‐co‐(2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid)]

Abstract

Summary: Novel polyfunctional sulfone‐ and anhydride‐containing reactive terpolymers with different compositions have been synthesized by complex‐radical polymerization of the ternary MA‐St‐APMS acceptor‐donor‐acceptor monomer system. This method allows preparing terpolymers with a sufficiently high content of APMS which essentially increased polyelectrolyte, swelling, IEC and thermal stability of terpolymer films. The terpolymer structure‐composition‐properties (polyelectrolyte, thermal, swelling and cation exchange behavior) relationships were studied by FTIR and 1H{13C} NMR (DEPT‐135) spectroscopy, viscometry, DSC‐TGA methods, and by means of swelling and exchange capacity. The observed H‐bonding between sulfonic acid, amide and anhydride fragments played an important role in the formation of the physically crosslinked and self‐assembled architectures with controllable hydrophilic‐hydrophobic balance. These reactive terpolymers can be used as synthons for exchange membrane preparation and fuel cell applications.

Poly(acrylamide-co-2-acrylamido-2-methyl-1-propanesulfonic Acid) Nanogels made by Inverse Microemulsion Polymerization

“…The increasing thermal stability at higher temperature may be due to the presence of sulfonic groups in side chain, which form cross-links. Also, it is well known that H-bonds as a variety of intermolecular interaction, exert essential influence on chemical structure of polymer formation (47). Due to the formation of H-bonds, physical, physico-chemical, spectral and thermal properties of co-polymers/polymers can be changed essentially.…”

Synthesis and fabrication of high‐potent antimicrobial polymeric ultrathin coatings

“…[28][29][30][31][32][33][34][35][36][37] MA and AM were taken in equal molar ratio and copolymerized. [39][40][41][42][43] Similarly, the chemical shift at 41 δ and 68 δ is attributed to tertiary carbon of MA ( 1,4 C) and AM ( 6 C). The concentration of initiator (AIBN) was varied from 0.0001 to 0.001 M. The highest % yield was achieved at 0.0003 M of initiator (AIBN).…”

“…The optimization of the copolymer was done with respect to different concentrations of the initiator. The chemical shift observed at 31 δ is assigned to the secondary carbon ( 5 C) of the polymer chain backbone 28,[39][40][41][42][43] (Figure 4). As the concentration of initiator (AIBN) increased from 0.0001 to 0.0003 M, the % yield was increased from 90 to 98% because of the availability of enough free radicals for polymerization.…”

“…13 C-NMR spectrum of the copolymer. Similarly, CH 2 stretching is observed at 2931 and 2864 cm −1 , respectively28,[38][39][40][41][42][43] (Figure 2).The chemical shifts at 2.1 δ and 3.2 δ are due to the protons bonded to the tertiary carbon of AM ( 6 CH) and MA unit ( 1,4 CH). Similarly, the peak at 1610 and 1680 cm −1 is attributed to C C and C O stretchings.…”

Physically and Chemically Cross‐Linked Poly{[(maleic anhydride)‐alt‐styrene]‐co‐(2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid)}/Poly(ethylene glycol) Proton‐Exchange Membranes

“…Recently, we have reported the synthesis of poly[(maleic anhydride)‐ alt ‐styrene‐ co ‐(2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid)] terpolymer [poly[(MA‐ alt ‐S)‐ co ‐AMPS]] as a potential precursor for the preparation of novel PEMs 38–40. Details of synthesis and characterization of the poly[(MA‐ alt ‐S)‐ co ‐AMPS] terpolymer were published in our previous paper 40. As the second step, we have prepared PEMs from these poly[(MA‐ alt ‐S)‐ co ‐AMPS]/PEG terpolymer precursor by using PEG.…”
