Phosphorus-containing polymers synthesised via nitroxide-mediated polymerisation and their grafting on chitosan by grafting to and grafting from approaches

Abstract

The phosphorus-based methacrylate monomers (h)MAPC1 have been polymerized by NMP and grafted on chitosan.

Perspective on the controlled polymer‐modification of chitosan and cellulose nanocrystals: Towards the design of functional materials

“…The final amount of grafted PMAPC1 was 28 and 35 wt.% for PhMAPC1. [41] Using chitosan, we have also developed macroparticles modified with grafts of poly (4-vinylpyridine) (P4VP) using RAFT via grafting from approach. In this case, chitosan macroparticles were made first prior to being functionalized with a 4-(phenylcarbonothioylthio)pentanoic acid (CPA), which is a RAFT transfer agent.…”

“…In this case, chitosan macroparticles were made first prior to being functionalized with a 4-(phenylcarbonothioylthio)pentanoic acid (CPA), which is a RAFT transfer agent. Once the macroparticles modified with CPA were obtained, the grafting polymerization S C H E M E 9 Synthesis scheme for the modification via grafting to and the grafting from of CTS with PMAPC1 and hPMAPC1 phosphonated polymers [41] was investigated at 10 and 40 h, yielding CTS-CPS-g-P4VP (see Scheme 10). Since it was not possible to cleave the grafted chains from the chitosan particles surface and determine their degree of polymerization, free CPA (sacrificial CTA) was added to the reaction mixture in order to estimate the molecular weight distribution to produce free polymer, assuming they will grow similarly to the grafted chains and have a rough estimate of the DP n of the grafted P4VP.…”

“…[ 42 ] Modified chitosan with phosphorous groups also may be a promising candidate for applications in wastewater treatment, anticorrosion of coatings, or as flame retardancy material. [ 41 ]…”

Synthesis of fluorinated phosphorus-containing copolymers and their immobilization and properties on stainless steel

“…There are a few reports on the homopolymerization of hepta-decauorodecyl methacrylate (HDFDMA), using AIBN as an initiator in supercritical carbon dioxide. 36,37 Canniccioni et al 25 reported the synthesis of (dimethoxyphosphoryl)methyl methacrylate (DMPMM) homopolymer by RAFT polymerization and Solimando et al 38 by nitroxide-mediated polymerization. There are no reports of their copolymerization.…”
