This review highlights the synthesis of biobased monomers from renewable resources for preparation polymers by (mini)emulsion and suspension polymerizations.
Biobased materials, derived from biomass building blocks, are essential in the pursuit of sustainable materials. Eugenol, a natural phenol obtained clove oil, but also lignin depolymerization, possesses chemical structure that allows its easy modification to obtain broad and versatile platform biobased monomers. In this Perspective, an overview variety reactions have been executed on allylic double bond, hydroxyl group, aromatic ring, methoxy group is given, focusing our attention those...
Solution polymerization of methyl acrylate initiated by 2,2'-azobis(isobutyronitrile) (AIBN) at 65 °C in the presence molecular iodine I2 has been studied. The process, called reverse transfer (RITP), efficiently controls weight (determined size exclusion chromatography, SEC) and structure polymer. For instance, poly(methyl acrylate) samples Mn,SEC = 5700 g mol-1 Mw/Mn 1.79 (Mn,theoretical 5500 mol-1), 10 900 1.91 500 21 800 1.98 20 700 mol-1) were successfully prepared. was followed on-line...
The kinetics of the living radical polymerization n-butyl acrylate (BuA) in presence an excess N-tert-butyl-N-(1-diethylphosphono-2,2-dimethylpropyl)-N-oxyl (DEPN) as a rate moderator has been studied temperature range 115−125 °C. equilibrium constant K = kd/kc between dormant and active chains was determined experimentally from slope ln([BuA]0/[BuA]) vs time. It obeys following Arrhenius relation: 4.93 × 105 exp(−119.3 kJ mol-1/RT), i.e., 1.09 10-10 mol L-1 at 125 Some straightforward...
The polymerization of methyl methacrylate (MMA) initiated by 2,2'-azobis(isobutyronitrile) (AIBN) as radical initiator in the presence iodine (I2) was studied at different temperatures (T = 70 °C and 80 °C). This process, called reverse transfer (RITP), is based on direct reaction radicals with molecular iodine. RITP efficiently controls weight (determined size exclusion chromatography, SEC) structure polymer chains (confirmed 1H 13C NMR spectroscopy). For instance, PMMA samples Mn,SEC 2300...
Mass spectrometry techniques, specifically matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) and electrospray ionization (ESI-TOF) are of considerable interest for characterizing very attractive polymers resulting from controlled radical polymerizations (CRP). This work proposes a systematic experimental comparison both methods to analyze polystyrene prepared by five different CRP: nitroxide-mediated polymerization (mediated...
Vegetable oils and lipids, terpenes, lignin derivatives, carbohydrates, proteins are used as biomass feedstock to prepare new bio-based monomers for radical polymerization in aqueous dispersed media, producing latexes.
This paper summarizes the work carried out during 3 years in a Network of program "Human Capital and Mobility" European Union CHRX 93-0159 entitled "Reactive surfactants heterophase polymerization for high performance polymers". A series about 25 original papers will be published open literature under general title this feature article from Part I to XXV. The synthesis selected either anionic or non ionic, as well inisurfs (both initiators surfactants), transurfs transfer agent surfactants)...
Abstract The kinetics of the iodine transfer polymerization (ITP) vinylidene fluoride (VDF) was achieved in presence three different chain‐transfer agents (CTAs): 1‐iodoperfluorohexane (C 6 F 13 I), 1‐iodo‐2 H, 2 H ‐perfluorooctane CH CF and 1,1,2,2‐tetrafluoro‐3‐iodopropane (HCF I). ITPs VDF carried out C I showed following: (1) a linear increase DP n versus α , which evidenced controlled character ITP, although polydispersity indices were slightly high (ca 1.5), (2) theoretical values...
Abstract Eugenol, a natural phenol currently mainly obtained from clove oil, is an interesting aromatic building block for the synthesis of novel biobased monomers. It can also be lignin depolymerization, becoming promising due to availability as biomass feedstock. The eight monomers derived eugenol containing polymerizable functional groups achieved. (meth)acrylation eugenol, isoeugenol, and dihydroeugenol performed solution homopolymerization these studied. Moreover, aiming prepare...
Cellulose nanocrystals (CNC) offer unique mechanical and optical properties but face challenges that often prevent its commercial development, foremost high hydrophilicity, which makes it incompatible with most polymers. Covalent polymer graft modification can address this issue; however, these processes are complex expensive. We present a simple, inexpensive route for the noncovalent of CNC surface block copolymers. Five new copolymers, composed butyl vinyl imidazolium bromide anchoring...
Abstract Poly(perfluorooctyl‐ethylenoxymethylstyrene) (PFDS) and poly(1,1,2,2‐tetrahydroperfluorodecyl acrylate) (PFDA) homopolymers as well poly(styrene)‐ b ‐poly(perfluorooctyl‐ethylenoxymethylstyrene) (PS‐ ‐PFDS) ‐poly(1,1,2,2‐tetrahydroperfluorodecyl ‐PFDA) block copolymers of various chain lengths were synthesized by nitroxide‐mediated radical polymerization in the presence either 2,2,6,6‐tetramethyl‐1‐piperidinyloxy free (TEMPO) case FDS monomer or N ‐ tert ‐butyl‐...
An ecofriendly and straightforward approach to prepare PNIPAM-functionalized mesoporous hybrid silica materials is described: the use of PEO-b-PNIPAM diblock copolymers, specifically designed act as efficient structure-directing agents (SDA) in synthesis, led directly functionalized materials, whose mesoporosity was subsequently created by washing material water appropriate conditions. Drug-loaded are usually obtained impregnating such a drug-containing organic solvent. To avoid step, an...
Biobased monomers have been used to replace their petroleum counterparts in the synthesis of polymers that are aimed at different applications. However, environmentally friendly polymerization processes also essential guarantee greener materials. Thus, photoinduced polymerization, which is low-energy consuming and solvent-free, rises as a suitable option. In this work, eugenol-, isoeugenol-, dihydroeugenol-derived methacrylates employed radical photopolymerization produce biobased polymers....
Abstract Hydrophilic/CO 2 ‐philic poly(ethylene oxide)‐ b ‐poly(1,1,2,2‐tetrahydroperfluorodecyl acrylate) block copolymers were synthesized via reversible addition–fragmentation chain transfer (RAFT) polymerization, iodine polymerization (ITP), and atom radical (ATRP) in the presence of either degenerative agents or a macroinitiator based on oxide). In this work, both RAFT ATRP showed higher efficiency than ITP for preparation expected copolymers. More detailed research was carried out...
Iodide does the job: Water-soluble, harmless, cheap, and nonhazardous NaI was used in combination with K2S2O8 instead of I2 itself to produce an uncolored living poly(butyl acrylate) latex controlled molecular weight by a single-step polymerization process (see scheme for one pathway). Reactivation polymer then yielded block-copolymer latex. BuA=butyl acrylate.
