Influence of acrylonitrile butadiene rubber on recyclability of blends prepared from poly(vinyl chloride) and poly(methyl methacrylate)

Abstract

The current investigation deals with the recycling possibilities of poly(vinyl chloride) and poly(methyl methacrylate) in the presence of acrylonitrile butadiene rubber. Recycled blends of poly(vinyl chloride)/poly(methyl methacrylate) are successfully formed from the plastic constituents, those are recovered from waste computer products. However, lower impact performance of the blend and lower stability of the poly(vinyl chloride) phase in the recycled blend restricts its further usage in industrial purposes. Therefore, effective utilisation acrylonitrile butadiene rubber in a recycled blend was considered for improving mechanical and thermal performance. Incorporation of acrylonitrile butadiene rubber resulted in the improvement in impact performance as well as elongation-at-break of the recycled blend. The optimum impact performance was found in the blend with 9 wt% acrylonitrile butadiene rubber, which shows 363% of enhancement as compared with its parent blend. Moreover, incorporated acrylonitrile butadiene rubber also stabilises the poly(vinyl chloride) phase present in the recycled blend, similarly Fourier transform infrared spectroscopy studies indicate the interactions of various functionalities present in the recycled blend and acrylonitrile butadiene rubber. In addition to this, thermogravimetric analysis indicates the improvement in the thermal stability of the recycled blend after the addition of acrylonitrile butadiene rubber into it. The existence of partial miscibility in the recycled blend was identified using differential scanning calorimetry and scanning electron microscopy.

Electrochemical inspection of polypyrrole/chitosan/zinc oxide hybrid composites

“…Consequently, inter‐polymer forces decreases, which ultimately minimizes the effective T g value of the composite. [ 61,62 ] When DSC measurement was performed on the PCZ composite observed an increase in the T g to 204.7°C (Figure 2d). In this case the observed increase in the T g can be related to the increased H‐bonding formation due to the inclusion of ZnO into the matrix of the PPy/Chy composite.…”

Dielectric properties of PANI‐PEG nanocomposites filled with silica media for antistatic applications

“…Polyethylene glycol (PEG) and polyaniline (PANI) are essential materials used in a variety of industries, including electronics and packaging. [1][2][3][4][5] Numerous characteristics, including the structural, dielectrical, and morphological ones, have been improved. Several strategies, including the addition of inert fillers, block copolymers, the blending of polymers, and the addition of plasticizer, have been researched to improve the properties of the polymer matrix.…”

“…A more uniform coverage of monomers into the Silica pore walls revealed this phenomenon, which had already been established in the literature 31-33 and 34-37. The majority of the samples demonstrate that the bond Si-O is characterized by three significant peaks at 440, 800, and 1090 cm À1 4,[38][39][40]. These bands can be seen as the symmetric stretching motion, the antisymmetric stretching motion, and the oxygen atoms moving perpendicular to the Si-O-Si plane rocking.Si-OH, Si-CH 3 , and Si-CH 3 (or -CH 2 -) group stretching vibrations can be attributed to three peaks that are measured at 955, 1260, and 2970 cm À1 7,9,10,41.…”
