We report the synthesis of thermophilic poly(N-acryloylglycinamide) (PNAGA) microgels that swell in water upon heating and their use as nanocatalyst hosts. The microgels are prepared by aqueous precipitation polymerization below the UCST phase transition temperature of PNAGA. The diameters of the P...
Glycinamide hydrochloride (Bachem) and acryloyl chloride (Sigma Aldrich) were used as received. N-acryloylglycinamide (NAGA) monomer was prepared as described earlier [19]. N,N′-methylenebis(acrylamide) (BIS, Merck) was recrystallized from methanol. Ammonium persulfate (APS, Merck) was recrystallize...
In this work, we have fabricated hybrid double-network hydrogels with ionically cross-linked κ-carrageenan as the first network and covalently cross-linked poly(N-acryloyl glycinamide) (PNAGA) as the second network by using an one-pot method. Because of synergistic interaction between κ-...
Poly( N -acryloylglycinamide-co-acrylonitrile) (poly(NAGA-AN)) copolymers were synthesized using reversible-addition-fragmentation transfer polymerization. In contrast to poly(NAGA) the thermoresponsive behavior of poly(NAGA-AN) shows a narrow cooling/heating hysteresis in water with a tunable cloud ...
Poly(N-acryloylglycinamide-co-acrylonitrile) (poly(NAGA-AN)) copolymers were synthesized using reversible-addition-fragmentation transfer polymerization. In contrast to poly(NAGA) the thermoresponsive behavior of poly(NAGA-AN) shows a narrow cooling/heating hysteresis in water with a tunable cloud point...
In this context, polyvinylidene fluoride (PVDF) UF membranes with enhanced hydrophilicity were modified by grafting hydrophilic poly (N-acryloyl glycinamide) (PNAGA) hydrogel formed through multi-hydrogen bond self-assembly via ultraviolet (UV)-initiated radical graft polymerization. Fourier transform ...
In the presence of water, poly(N-acryloyl glycinamide) homopolymers form highly swollen hydrogels that undergo fast and reversible gel↔sol transitions on heating. According to the literature, the transition temperature depends on concentration and ave
