ABSTRACT Polymeric materials, in particular PVC, can find various industrial utilizations thanks to the use of plasticizers added during their processing. The most famous applications include wires and cables, coatings, flooring, paintings, packaging… After some generalities concerning plasticization theories description plasticized petro‐ bio‐based polymers, this review details well‐known different petro‐based more particularly phthalates which represent important category PVC plasticizers....
Abstract A novel vegetable oil‐based polyamine issued from grapeseed oil (GSO) was prepared using cysteamine chloride (CAHC) by thiol‐ene coupling (TEC). The structure of the (AGSO) carefully examined a large range chemical analyses (FTIR, 1 H NMR and 13 C NMR, LC‐MS…). effects amination GSO on properties were also studied viscosimetry. Then, AGSO employed as curing agent for bio‐based epoxy resin. thermal crosslinking reaction between epoxidized linseed (ELO) DSC rheology. This study dealt...
Before surgery, the best strategy for managing patients who are taking renin-angiotensin system inhibitors (RASIs) (angiotensin-converting enzyme or angiotensin receptor blockers) is unknown. The lack of evidence leads to conflicting guidelines.
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...
Abstract Polyurethanes cover a large range of materials exhibiting various physical and mechanical properties making them useful in different applications such as elastomers or biomaterials, for instance. The introduction ionic groups the polyurethane backbone opens way to new where can act crosslinkers that greatly modify final thermal materials. Furthermore, hydrophilicity chains be enhanced by presence species, so processed conventional dispersions even polar solvent water. As consequence...
This contribution deals with the self-assembling of a terpolymer on titanium oxide (TiO2) surface. The polymer structure was obtained by polymerization different methacrylates, i.e., alkyl-phosphonated, butyl and PEG methacrylate, in presence chain transfer agent. resulting PEG−poly(alkyl phosphonate) material, characterized mainly SEC NMR, self-organized at interface TiO2. AR-XPS demonstrated binding phosphonate groups to TiO2 substrate formation PEG−brush layer outermost part system....
Besides usual coupling agents such as, for instance, silane, thiol, or carboxylic acids, phosphonated-based low molecular weight molecules and polymers appear of great interest the modification metal oxides. In contexts, this Review is focused on use phosphonated derivatives surface treatment oxides as compounds are known to establish strong stable links with inorganic phases. Functionalization leads obtaining hybrid materials that can find applications in numerous fields. As a result, an...
We report the simple synthesis of tractable and high ion conducting PMMA-silica nanocomposites achieved by sol−gel processing. Mechanical strength was obtained incorporating silica nanofillers covalently bonded to polymer chains, whereas flexibility, thermal stability, ionic conduction were provided liquid.
The RAFT polymerization of dimethyl(methacryloyloxy)methyl phosphonate (MAPC1) using dithioester chain transfer agents is reported for the first time to our knowledge in literature. Poly(dimethyl(methacryloyloxy)methyl phosphonate) (PMAPC1) was synthesized DMF at 70 °C with a good control over molecular weight, latter ranging from 8000 24 000 g mol−1. Polymers were characterized by 1H and 31P NMR, size exclusion chromatography both refractive index triple detection. effect solvent also...
The processing of recycled poly(ethylene terephthalate) (PET) involves thermal and hydrolitic degradation a polymer, which reduces the molecular weight, intrinsic viscosity, mechanical properties materials. Degradative effects can be limited by using chain extenders. Preliminary tests show that diisocyanates are more reactive toward end groups virgin PET than bis-oxazolines or diepoxides under experimental conditions used. So, samples modified with possess weight viscosity (Mw > 60,000 g/mol...
A sol–gel synthesis using modified poly(methyl methacrylate) (PMMA) bearing trimethoxysilane groups and tetraethoxysilane (TEOS) allowed immobilization of very high loadings ionic liquid [BMIm][NTf2] within nanocomposite PMMA-silica membranes. The (IL) provided both flexibility conductivity, while the silica nanofiller covalently bonded to polymer chains maintained mechanical strength, as shown by a DMA tensile test. Complex impedance spectroscopy evidenced critical threshold in conductivity...
Well-defined graft copolymers were obtained using a copper-catalysed azide–alkyne Huisgen's cycloaddition click reaction from both biocompatible and non-toxic poly(ε-caprolactone) poly(2-methyl-2-oxazoline) homopolymers. Resulting amphiphilic proved to form micelles that could be used as potential drug carriers.
