“…[3] Furthermore, the development of PE/PET blends have been intensified as a result of the availability of both polymer components, i.e., PE and PET as a post consumer waste. [4] In addition, the recovery of plastic waste is often advantageous from both an economical and environmental point of view.…”

“…[4] In addition, the recovery of plastic waste is often advantageous from both an economical and environmental point of view. [3,4] However, the reprocessing of plastic wastes by a simple melt blending usually leads to poor physical properties of the products. [5,6] This is the case for PE/PET blends, which are characterized by gross phase segregation and a weak interfacial adhesion, because the two polymer components are immiscible and have extremely poor mechanical properties.…”

Summary: This work is aimed at studying the morphology and the mechanical properties of blends of low density polyethylene (LDPE) and poly(ethylene terephthalate) (PET) (10, 20, and 30 wt.‐% of PET), obtained as both virgin polymers and urban plastic waste, and the effect of a terpolymer of ethylene‐butyl acrylate‐glycidyl methacrylate (EBAGMA) as a compatibilizer. LDPE and PET are blended in a single screw extruder twice; the first extrusion to homogenize the two components, and the second to improve the compatibilization degree when the EBAGMA terpolymer is applied. Scanning electron microscopy (SEM) analysis shows that the fractured surface of both the virgin polymer and the waste binary blends is characterized by a gross phase segregation morphology that leads to the formation of large PET aggregates (10–50 µm). Furthermore, a sharp decrease in the elongation at break and impact strength is observed, which denotes the brittleness of the binary blends. The addition of the EBAGMA terpolymer to the binary LDPE/PET blends reduces the size of the PET inclusions to 1–5 µm with a finer dispersion, as a result of an improvement of the interfacial adhesion strength between LDPE and PET. Consequently, increases of the tensile properties and impact strength are observed.

Abstract. Degradation of different polymers now a day is the most crucial thing to carry out. It possesses threats to human health as well as to the environment. Different polymers like PVA, PVC, and PP with high density and low density are one of the most consumed by population and also their degradation is a bit difficult. For this many people have started working on effective methods of degradation of these polymers. This can be done by thermal degradation and pyrolysis which requires high temperature, bio degradation using starch, bacteria etc and photo degradation. Traditional gravimetric and respirometric techniques are the methods currently used in testing. They fit readily for degradable polymeric materials usually. Also they are well suited for biodegradable components with polymer blends. But the recent polymer generation is comparatively resistant to bio degradation of polymers hence they cannot be used here. The polymer matrices are readily present in the plasticizers boosting the strength of polymeric material hence in addition; there is the mechanism of degradation. The information on various methods discussed in this review is planned to illustrate a best fit of methods for those who are interested in testing the degradation of polymers under different environmental conditions and selection of appropriate technique for specific combination of mixture of polymer and catalysts which helps to degrade the polymeric material.

“…In the thermal degradation free of solvent, the primary radicals may abstract a secondary hydrogen atom of a different molecule (intermolecular hydrogen transfer) producing an nparaffin and a more stable secondary radical. This reaction is less influenced by the presence of a solvent, because the reaction media is more diluted, avoiding the intermolecular hydrogen transfer between chains [20,22].…”

“…However, investigations about degradation of polyolefins using solvents have been conducted to a lesser extent. Karaduman et al [19,20] studied the low density polyethylene (LDPE) cracking in cyclohexane. A study was also undertaken of the effect of dilution and thermal conditions on the high density polyethylene (HDPE) degradation in an inert solvent (phenyleter) and a hydrogen donor solvent such us tetralin [21].…”
