This in vitro study investigated the mechanical and structural characteristics of lignin-added PMMA resin composites at concentrations 1, 3, 5% by weight. Four sample groups were formed. For transverse strength test, specimens prepared accordance with ANSI/ADA specification number 12, for impact test ASTM D-256 standards used. With intent to evaluate properties strength, three-point bending (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...

Abstract In this study, nonmiscible polyvinyl chloride (PVC) and polymethyl methacrylate (PMMA) polymers were made miscible by using MA‐St‐MMA terpolymer as a compatibilizer. Maleic anhydride‐styrene‐methyl (MA‐St‐MMA) was synthesized in our laboratory used. The determined FT‐IR spectroscopy. Equal mass PVC/PMMA mixture samples prepared series the compatibilizer varying between 2% 10% added to effect of on miscibility viscometrically, thermally, mechanically and, visually. With addition...

AbstractAbstractIn the present paper, effects of reactive terpolymer containing maleic anhydride on thermomechanical properties PVC were investigated. The behaviour multicomponent blend based poly(vinyl chloride) (PVC), PVC/maleic anhydride–stryrene–methyl metacrylate (MA–St–MMA)/n–pentyl maleat–styrene–methyl metacrylate(nPnMA–St–MMA) studied using TMA method. blends prepared by changing weight ratio MA–St–MMA and nPnMA–St–MMA terpolymers, keeping content fixed at 75 wt-%. terpolymer, a...

AbstractThe copolymers of maleic anhydride (MA) are frequently used as a reactive polymer in the preparation functional polymers which active agents consisting amino or hydroxy groups can be linked to them via ring opening reactions. In present paper, allylpropionate-alt-maleic (MA-AP) copolymer was modified by hexamethylenediamine (HMDA) obtain poly(maleamidic acid-allylpropionate) (MAA-AP) MA-AP copolymer. Next, maleimide-allylpropionate (MI-AP) obtained heating MAA-AP The MA-AP, and MI-AP...

Recent advancements in nanotechnology have garnered increasing attention due to the improvements producing and utilizing particles whose sizes are extremely small. There is particular interest metal nanoparticles their distinctive properties. Silver (Ag-NPs) been of owing unique electrical, optical physicochemical properties as well biomedical applications. Ag-NPs fastest growing class nanoscale materials because antibacterial activities. They now considered be next generation...

In the present study, tensile bond strength between on acrylic resin and a soft liner, molloplast B, was studied. To enhance bonding capacity these materials, surface modified using ethyl methacrylate, iso-butyl methacrylate or tert-butyl monomers. The monomers were applied onto surfaces of components for 60, 120 180 s values obtained. statistically compared. Changes investigated by fourier transform infared spectroscopy with attenuated total reflectance (FTIR-ATR). highest value obtained...

Immıscible polymethyl methacrylate/polystyrene (PMMA/PS) mixtures with various maleic anhydride-styrene-methyl methacrylate (MAStMMA) compatibilizer ratio (0, 2, 4, 6, 8 and 10) % were obtained by solution casting. The spectral results showed that the optical constants such as refractive index (n), extinction coefficient (k) absorption increase increasing terpolymer ratio. On other hand, energy gap Eg an inverse trend to concerning constants. lowest observed was between 10

The green synthesis of gold nanoparticles (Au-NPs) was carried out by pouring the aqueous extract East Anatolian origin Asphodelus aestivus plant onto metal ions and reducing them via single-step one- pot method. absorption peak synthesized gave a maximum at 575 nm. All X-ray diffraction peaks 2θ = 38.25 , 44.46 64.64 77.20 that index to (111), (200), (220), (311) planes verify successful Au-NPs. Mostly spherical shape particles showed homogeneous distribution with size range 20±5 nm are...

The blending effect of poly maleic anhydride-styrene-methyl methacrylate (MA-St-MMA) terpolymer on non-miscible PVC and Polystyrene was studied depending their thermomechanical properties. Depending the amount synthesized used compatibilizer tensile strength, modulus, properties blends are enhanced. unmodified with small amounts exhibit two-step degradation whereas those containing 6, 8 10 percent showed a single glass transition (Tg). All results reveal that PS/PVC mixtures modified...

In this study, an electron-acceptor monomer Fumaronitrile (FN), and 3 electron-donor monomers; Trans-Anethole (ANE), Vinyl-iso-butylether (VIBE) Trans-Stilbene (Stb) were polymerized by free radical polymerization charge transfer complex (CTC) mechanism. content ratio, FT-IR, H-NMR, average molar weight, thermal mechanical analyzes of the obtained FN-ANE-VIBE-Stb quaterpolymer performed. The synthesized was in resin form. rate fumaronitrile chain determined as approximately 50%. properties...

In this study, Maleic anhydride/Styrene (MAS) copolymer was synthesized. The synthesized characterized and then modified with two different primary alcohols (propyl butyl). Dissolution, FT-IR thermo-mechanical (TMA) analyzes of the its ester derivatives were performed. numbers obtained calculated. Although showed dissolution behavior in same solvents as MAS copolymer, they dissolved faster. Modification confirmed spectra. It also found that more elastic than had a lower glass transition...

In this study, polyvinyl chloride (PVC) and polystyrene (PS) polymers, which do not form a compatible blend with each other in certain concentration ranges are widely used on an industrial scale, were used. The range these two polymers determined viscometrically, maleic anhydride-styrene (MAS) copolymer was added as compatibilizing agent range. the polymer pair did 1.5 2.0 g dL-1. range, 5.0 10.0 % MAS to couple its effect investigated. It by viscometric method that good compatibilizer where blend.
