N-ACRYLOXYSUCCINIMIDE, with the chemical formula C7H7NO3 and CAS registry number 38862-24-7, is a compound known for its applications in various chemical processes. This white crystalline solid, also referred to as NAS, is characterized by its acryloxy and succinimide functional groups. It is...
Kinetics of solution (co)polymerization of N -vinyl pyrrolidone (NVP, or V) and N -acryloxy succinimide (NAS, or A) have been investigated at 60°C in N, N -dimethylformamide with 4,4′-azobis(4-cyanopentanoic acid) as initiator. First, the ja:math value for homopolymerization of A ...
The reversible addition-fragmentation chain transfer (RAFT) polymerization process was used to synthesize well-defined N-acryloxysuccinimide (NAS) bas…[ Arnaud FavierFranck D'AgostoMarie-Thérèse CharreyreChristian Pichot]PolymerA. Favier, F. D'Agosto, M.-T. Charreyre, C. Pichot, Synthesis of...
The grafting reaction of oligodeoxyribonucleotides (ODN) on N-vinyl pyrrolidone (NVP)/N-acryloxy succinimide (NAS) copolymers has been investigated. First, NVP/NAS copolymers were prepared by free-radical polymerization in N,N-dimethylformamide (DMF); characterization of the monomer sequence ...
(NAM-co-NAS)copolymers with full control of composition and MW.These copolymer chains with regularly-distributed reactive functions can be integrated into more complex architectures.As an example,poly[(NAM-co-NAS)-fr-NAM] block copolymers with length-varying poly(NAM)block were synthesized with a...
A correlation between the synthesis conditions – composition of the reactive solution – chemical characteristics of the reactive polymer monoliths – nitrogen/NAS content – and the reversed-phase separation properties of the functionalized monolithic columns – selectivity towards homologous series of ak...
Biotin–streptavidin association is employed as a model system to investigate both selective binding and the relevant signal‐to‐noise (S/N) ratio. When the molar feed ratio of NAS and OEGMEMA is 2:8, the copolymeric film is optimized to give the highest S/N ratio (339.8) according to...
000gmol, and low polydispersity index (/-NAS) block copolymers were synthesized by a two step method, in which a poly(DMA) homopolymer was prepared first and then used as macro-chain transfer agent to polymerize NAS. For example, a poly(DMA--NAS) sample was obtained with an average ...
Poly(N-acryloxysuccinimide) (PNAS) and poly(N-acryloxysuccinimide-co-N-vinylpyrrolidone) (P(NAS-co-NVP)) of adjustable molecular weights and narrow polydispersities were prepared by nitroxide-mediated polymerization (NMP) in N,N-dimethylformamide in the presence of free SG1 (N-tert-butyl-N-...
