“…Patrick diagram (Figure ), which correlates the most important properties of composites, impact strength, and tensile strength, allows choosing the SBS dosage for different applications of the composites depending on the priority property. As can be observed, the WEEE composite containing 15% SBS and 5% SEBS‐g‐MAH presents tensile and impact strength compared to high‐impact polystyrene obtained by bulk/suspension polymerization . Considering HIPS application for covers, housings, packaging, and small automotive parts, the obtained materials can be considered as an alternative for virgin HIPS.…”

The reuse of plastic components of waste electrical and electronic equipment (WEEE) is an important concern both for environmental issues and to preserve the material resources, with minimum energy consumption. Considering that polystyrene fraction was reported as approximate 80% of the total amount of WEEE plastic, this article aims to evaluate the recycling of this fraction, without separation by components, by melt compounding with styrene-butadiene block-copolymer (SBS) and hydrogenated and maleinized SBS, the blend of the two elastomers acting both as an impact modifier and compatibilizer. The composites are characterized by mechanical analysis, impact tests, dynamic mechanical analysis, differential scanning calorimetry, thermogravimetric analysis, scanning electron microscopy, energy dispersive X-ray analysis, and X-ray diffraction. The recycling conditions of the polystyrene fraction as composites without eliminating the WEEE additives for improved UV and flame resistance, with physical mechanical properties comparable to those of high-impact polystyrene resulted from the study.

“…In previous decades, high‐performance polymers such as polyether ether ketone (PEEK), polyphenylene sulfide (PPS), polyetherimide (PEI), and polymethacrylimide (PMI) have been employed to manufacture critical components in the medical, automotive, and aerospace industries. [ 1–5 ] Their unique properties include a high strength‐to‐weight ratio and outstanding thermal, chemical, and physical stress resistance, leading to the replacement of metals with these polymers in several industrial applications. [ 6 ] One of their key features is high thermal stability, typically combined with a high glass transition temperature ( T g ), which is closely linked to their mechanical properties.…”

High‐performance polymers such as polymethacrylimides have outstanding properties, for example, a unique strength‐to‐weight ratio and a high thermal stability, usually coupled to a high glass transition temperature. However, the requirement of high processing temperatures caused by these high glass‐transition temperatures is often not desired for melt extrusion processes. Herein, a novel and straightforward imidization process of poly(methacrylic anhydrides) is presented with different ratios of ammonia and N‐isopropylamine that is induced by thermal treatment. Therefore, polymethacrylimides with a varying degree of N‐substitution, and thus a varying number of hydrogen‐bond‐donating moieties, are synthesized under facile reaction conditions. An in‐depth investigation into the structures obtained with this new methodology is undertaken via a combination of nuclear magnetic resonance spectroscopy (NMR), Fourier‐transform infrared spectroscopy (FT‐IR), and high‐resolution electrospray ionization mass spectrometry (ESI‐MS). Additionally, thermal properties of the materials are investigated using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) analyses. These latter measurements highlight the key opportunity available with this novel synthesis to tailor the thermal properties of the polymer by providing a clear correlation between hydrogen bond formation, as observed by FT‐IR, and the glass transition temperature.

“…The basic groups of application of polymeric materials in technology result from their specific functional properties. Most often they are used in the following areas: construction [ 2 , 3 ], medicine [ 4 ], agriculture [ 5 ], food [ 6 ], household [ 7 ], automotive [ 8 , 9 ] and chemical [ 10 ]. The application of plastic as packaging items is especially important, with around 40 million tonnes of plastic film produced from polyethylene alone [ 11 ].…”

Lifetime Prediction Methods for Degradable Polymeric Materials—A Short Review

The determination of the secure working life of polymeric materials is essential for their successful application in the packaging, medicine, engineering and consumer goods industries. An understanding of the chemical and physical changes in the structure of different polymers when exposed to long-term external factors (e.g., heat, ozone, oxygen, UV radiation, light radiation, chemical substances, water vapour) has provided a model for examining their ultimate lifetime by not only stabilization of the polymer, but also accelerating the degradation reactions. This paper presents an overview of the latest accounts on the impact of the most common environmental factors on the degradation processes of polymeric materials, and some examples of shelf life of rubber products are given. Additionally, the methods of lifetime prediction of degradable polymers using accelerated ageing tests and methods for extrapolation of data from induced thermal degradation are described: the Arrhenius model, time–temperature superposition (TTSP), the Williams–Landel–Ferry (WLF) model and 5 isoconversional approaches: Friedman’s, Ozawa–Flynn–Wall (OFW), the OFW method corrected by N. Sbirrazzuoli et al., the Kissinger–Akahira–Sunose (KAS) algorithm, and the advanced isoconversional method by S. Vyazovkin. Examples of applications in recent years are given.
