Thermodynamic Miscibility and Thermal and Mechanical Properties of Poly(ethylene‐co‐vinyl acetate‐co‐carbon monoxide)/Poly(vinyl chloride) Blends

Abstract

This paper reports the miscibility and thermal and mechanical properties of solution cast binary blends of poly(ethylene-co-vinyl acetate-co-carbon monoxide) (EVACO) and poly(vinyl chloride) (PVC). The composition of these blends was varied from 10:90 to 90:10 of PVC/EVACO (w/w %). Fourier transform infrared spectroscopy revealed an extensive intermolecular attraction between the blend components, which accounts for their mutual solubility. The differential scanning calorimetry study revealed that the blend components are miscible with each other in all proportions as they exhibited a single glass transition temperature. Tensile strength, moduli, and thermal stabilities of these blends significantly improved with increasing proportion of

Selective dispersion of carbon fillers into dynamically vulcanized rubber/plastic blends: a thermodynamic approach to evaluate polymer reinforcement and conductivity enhancement

“…This can be explained due to the attainment of higher randomness into the TPV systems through dynamic vulcanization as well as by progressive ller addition, leading to the disruption of EOC crystallites. 56 Similarly, the T c values, obtained from cooling exotherm (Fig. 14(B)), have depicted similar trend as observed in the melting endotherm (Fig.…”

Influence of multiwalled carbon nanotubes on the structure and properties of poly(ethylene‐co‐vinyl acetate‐co‐carbon monoxide) nanocomposites

“…The intense peak at 2 θ = 20.83° is due to the (110) plane of polyethylene crystallites, since the polyethylene segments impart crystallinity in EVACO. [ 55 ] The crystallinity of EVACO/m‐MWCNT composite increases as the filler content increases, as presented in Table 1. This increase in crystallinity is observed up to a filler loading of 0.1%, thereafter it decreases.…”

Development of novel polar thermoplastic vulcanizates based on ethylene acrylic elastomer and polyamide 12 with special reference to heat and oil aging

“…Shore D hardness of V 50 P 50 PE 4 is 44; which is 33 for V 70 P 30 PE 4 TPV. Such improvement in mechanical properties from V 70 P 30 PE 4 TPV to V 50 P 50 PE 4 TPV may be of two reasons (a) higher PA12 fraction (plastic phase) or (b) higher degree of cross‐linking in the AEM rubber phase.…”
