In some cases, blends containing PVC and LLDPE show low compatibility. Adding styrene-butadiene rubber to the PVC/LLDPE mixtures leads to a noticeable increase in tensile strength and compatibility of the blends. Also, an improvement in tensile strength is observed after incorporating SBR compatibilizer resulting in entirely different gamma irradiation doses. Without a compatibilizer, the mixture exhibits a distributed PVC and LLDPE phase with variable sizes and shapes; even a sizable portion of the domains resemble droplets. Styrene butadiene rubber (SBR) and gamma radiation make mixtures of (PVC/LLDPE) more compatible. The SEM study of the blends demonstrated that adding the compatibilizer resulted in finer blend morphologies with less roughness. At the same time, gamma irradiation reduced this droplet and gave a more smooth surface. Poly(vinyl chloride) (PVC) was chemically modified with four different amino compounds, including ethylene diamine (EDA), aniline (An), p-anisidine (pA) and dimethyl aniline (DMA) for improving the electric conductivity and oil removal capability of the blend polymer. All ionomers were prepared by nucleophilic substitution in a solvent/non-solvent system under mild conditions. This work novelty shows a sustainable route for producing oil adsorption materials by recycling plastic waste. After the amination process of poly(vinyl chloride) the oil adsorption was significantly enhanced.

Hydrogel membranes are currently attracting significant attention due to their versatile 3D network structures capable of adsorbing water and various dissolved compounds. In this study, a pH-sensitive hydrogel membrane was developed by combining sodium alginate (SA) molecules with poly(vinyl alcohol) (PVA) for water purification applications. We investigated the physicochemical characteristics of the SA/PVA membranes, including equilibrium swelling, gel fraction, and water absorption. We also examined the influence of freeze−thaw cycles on pore size and morphology. SEM imaging revealed that the pore size increases with the number of cycles, while FTIR results confirmed the presence of intermolecular hydrogen bonding between the PVA and SA chains. The SA/PVA hydrogel membrane demonstrated remarkable pH sensitivity from pH 1 to 11. The SA/PVA hydrogel membrane showed significant potential for removing toluidine blue (TB) dye from aqueous solutions. The adsorption kinetics were studied using pseudo-first-order and pseudo-second-order models, with the latter offering a superior fit to the experimental data (R 2 = 0.97). Furthermore, adsorption isotherm modeling indicated monolayer adsorption on homogeneous sites and multilayer adsorption on heterogeneous sites. The Langmuir isotherm model provided a maximum adsorption capacity (q m ) of 74.1 mg/g, and the Freundlich isotherm model exhibited a correlation coefficient (R 2 ) of 0.89.
