Mazhar, Hassam et al. “Thermal Degradation Kinetics Analysis of Ethylene-Propylene Copolymer and EP-1-Hexene Terpolymer.” Polymers vol. 14,3 634. 7 Feb. 2022, doi:10.3390/polym14030634
Abstract. This paper reports the in-situ synthesis and thermal degradation studies of the ethylene-propylene copolymer and ethylene-propylene-1-hexene terpolymer and its nanocomposite with ZnAL LDH sheets. The 1-hexene dosing during the in-situ process influenced the product yield and immensely affected the thermal stability of the resultant polymer.
Zhang, Y., Kang, X., & Jian, Z. (2022). Selective branch formation in ethylene polymerization to access precise ethylene-propylene copolymers. Nature communications, 13(1), 725. https://doi.org/10.1038/s41467-022-28282-z
Abstract. Polyolefins with branches produced by ethylene alone via chain walking are highly desired in industry. Selective branch formation from uncontrolled chain walking is a long-standing challenge to generate exclusively branched polyolefins, however. Here we report such desirable microstructures in ethylene polymerization by using sterically constrained α-diimine nickel(II)/palladium(II) catalysts at 30 °C–90 °C that fall into industrial conditions.
Olejniczak K, Napiórkowski J. Wear Analysis of Materials Used for a Track Steering System in Abrasive Soil Mass. Materials (Basel). 2021 Oct 18;14(20):6164. doi: 10.3390/ma14206164.
Abstract. This paper presents the results of comparative research on materials used for a track steering system in an abrasive soil mass. Two types of elastomer tracks were tested: a steel-rubber stave from an asphalt paver and a rubber overlay used in vehicles with a steel track chain. The results obtained were related to the wear of Hadfield steel. The tests were carried out on a "spinning bowl" stand in a natural soil mass, which consisted of two types of soil: light and heavy.
Ulitzsch S, Bäuerle T, Stefanakis M, Brecht M, Chassé T, Lorenz G, Kandelbauer A. Synthesis of an Addition-Crosslinkable, Silicon-Modified Polyolefin via Reactive Extrusion Monitored by In-Line Raman Spectroscopy. Polymers (Basel). 2021 Apr 12;13(8):1246. doi: 10.3390/polym13081246.
Abstract. We present the modification of ethylene-propylene rubber (EPM) with vinyltetra-methydisiloxane (VTMDS) via reactive extrusion to create a new silicone-based material with the potential for high-performance applications in the automotive, industrial and biomedical sectors.

Abstract. This paper characterizes and analyzes the microstructures of injection-molded polypropylene parts reinforced with 20 wt% of hemp fibers in order to understand the process induced variations in thermomechanical properties.
Taraghi I, Paszkiewicz S, Irska I, Pypeć K, Piesowicz E. The Role of Interfacial Interactions on the Functional Properties of Ethylene-Propylene Copolymer Containing SiO2 Nanoparticles. Polymers (Basel). 2020 Oct 9;12(10):E2308. doi: 10.3390/polym12102308.
Abstract. In this paper, the mechanical properties, thermal stability, and transparency of ethylene-propylene copolymer (EPC) elastomer modified with various weight percentages (1, 3, and 5 wt.%) of SiO2 nanofillers have been studied. The nanocomposites were prepared via a simple melt mixing method.
