“…Plasticizers are usually inert organic compounds, with low molecular weight. To obtain a satisfactory result from this additive, it is required to have a group of characteristics in common with the polymer used, that is, polarity, solubility, structural configuration with similar chemical structure between them …”

“…To obtain a satisfactory result from this additive, it is required to have a group of characteristics in common with the polymer used, that is, polarity, solubility, structural configuration with similar chemical structure between them. [8] The performance of plasticizer is analyzed by the quantity used of it to acquire the desired mechanical properties, taking into account significant factors, such as chemical structure, polymer matrix, and other characteristics described above. [9] Therefore, the present research aims to analyze the most satisfactory compatibility between the expanded polystyrene and a plasticizer in order to obtain high quality paint.…”

Summary Expanded polystyrene (EPS) is a polymer with an extensive applicability, however the destination of its residues is little explored. Due to its negative consequences against the environment, an effective application for this waste is required. An example of this segment is the use of expanded polystyrene residue as the polymeric base of paint, aiming areas such as civil construction and wood industry. This research intends to analyze the use of different kinds of polymeric plasticizers, considering the use of aromatic and natural solvents. The main objective is to analyze the influence of each material taking into account properties like elasticity and adhesion on wood substrate. The studied plasticizers were: thermoplastic copolymers ESBR, SIS, SBS, SEBS and the epoxidized soybean oil (ESBO). The obtained results showed that the copolymer SEBS presented the most satisfactory performance, being compatible with the expanded polystyrene, providing a homogeneous base resin, which will be used for the paint formulation, considering the addition of pigments and additives.

“…These cases suggest that the plasticizer may function as a compatibilizer of the polymer blend. 11 As a higher value of dielectric constant and a low value of viscosity should result in higher conductivity, this study deals to find the combined effect of both these parameters by incorporating double plasticizers. However, it apparently reduces the mechanical stability of the electrolyte system and has a poor interfacial stability with the electrodes.…”

Polymer blend composed of poly(vinyl chloride) and poly(ethyl methacrylate) with lithium perchlorate (LiClO 4) and the plasticizer ethylene carbonate (EC) mixture with propylene carbonate, γ-butyrolactone (GBL), dibutyl phthalate and diethyl carbonate have been synthesized using the solution casting technique. Structural changes and thermal stability of the films were resolved using X-ray diffraction analysis and thermogravimetric/differential thermal analysis, respectively. The membrane that contains EC+ GBL exhibits maximum ionic conductivity of the order of 1.208×10 −3 S cm −1 at 303 K. The temperature-dependent ionic conductivity of the polymer membranes has been estimated using AC impedance analysis.

“…Various plasticizers including di-octyl adipate (DOA), di-octyl phthalate (DOP) and Bis(2-ethylhexyl) phthalate (DEHP) are usually added to PVC. Addition of these plasticizers improves the flexibility, processability and extensibility of the PVC products (Wojciechowska 2012). Besides, it facilitates microbial growth when PVC products are disposed into the environment (Nair et al 2009), thereby solving the issue of environmental pollution (Webb et al 1999;Gumargalieva et al 1999;Wojciechowska 2012).…”

The accumulation of plastics in the environment is raising great concerns with respect to long-term environmental, economic and waste management problems. The aim of the present research was to investigate the biodegradability of starch blended polyvinyl chloride films in soil burial and controlled laboratory experiments using selective fungal isolates. Clear surface aberrations as color change and minor disintegration in polyvinyl chloride films were observed after 90 days and later confirmed through scanning electron microscopy. The fungal strains showing prominent growth and adherence on plastic films were isolated. One of the strains showing maximum activity was selected and identified as Phanerochaete chrysosporium PV1 by rDNA sequencing. Fourier transform infrared spectroscopy and nuclear magnetic resonance analyses indicated considerable structural changes and transformation in films in terms of appearance of new peaks at 3,077 cm -1 (corresponding to alkenes) and decrease in intensity of peaks at 2,911 cm -1 (C-H stretching). It was supported with a significant decrease in the molecular weight of polymer film from 80,275 to 78,866 Da (treated) through Gel permeation chromatography in shake flask experiment. Moreover, the biodegradation of starch blended polyvinyl chloride films was confirmed through release of higher CO 2 (7.85 g/l) compared to control (2.32 g/l) in respirometric method. So fungal strain P. chrysosporium PV1 has great potential for use in bioremediation of plastic waste.
