“…In the last two decades, the interest in the synthesis of multifunction polymers derived from acrylate monomers, having long aliphatic alkyl chain, gained more attention because of their extended usage in different medical and industrial fields [1][2][3][4]. This type of polymers has remark-ably diverse, characteristic, sought-after properties, from hardness and strength, transparency, elasticity to superabsorbency [5][6][7].…”

The long-chain acrylate monomer, 2-ethylhexyl acrylate (EHA), was obtained by esterification of acrylic acid with 2-ethylhexanol, and the copolymer by free radical polymerization with N-isopropylmethacrylamide (PMA) in various proportions using azobisisobutyronitrile (AIBN) as the initiator in a benzene solvent. High conversion polymers were obtained: polyEHM, polyPMA, 3EHM/1PMA, 1EHM/1PMA and 1EHM/3PMA, which were named P1, P2, P3, P4 and P5, respectively. The chemical structure was confirmed by Fourier transform infrared spectroscopy (FT-IR) and proton nuclear magnetic resonance (1H-NMR). The percentage of nitrogen was used to determine the reactivity coefficient of EHA-co-PMA using the Kelin-Todosa method, rEHA = 1.14 and rPMA = 0.321. Based on the reactivity and solubility coefficients in the virgin SN 500 base oil, the performance of polymers, except P2, as additives to lubricating oils was assessed. Polymers with a high content of hydrophobic EHA monomer (P1 and P3) showed good performance as viscosity increasing and freezing point lowering agents, while P4 had the best anti-corrosion properties.

The miniaturization and high-power density of modern electronic devices pose significant thermal management issues, particularly affecting their performance and lifetime. Ladder-like polysilsesquioxanes (LPSQs) offer a promising solution due to their remarkable thermal, mechanical, and chemical properties. By incorporating thermally conductive fillers, LPSQ composites can achieve high thermal conductivity (TC), making them ideal for thermal management in advanced electronic applications. In this study, LPSQ-based nanocomposites containing functionalized alumina nanoparticles were prepared by solution casting and UV curing, and the effects of varying amounts of Irgacure-184 photoinitiator on their structural and thermal properties were investigated. Three sets of samples were prepared with a fixed amount of LPSQs, 80 wt.% of nanoparticles, and 1, 5, or 10 wt.% of photoinitiator with respect to the matrix. TC was evaluated from the measured values of heat capacity, density, and thermal diffusivity. TC values increased by 60%, 71.2%, and 93.1% for the three samples, respectively, compared to the neat matrix. Results indicate that an intermediate amount of photoinitiator (5%) preserved LPSQs’ structural integrity, namely the presence of long linear silsesquioxane chains, and provided good filler dispersion and distribution, high polymerization degree, thermal stability, and high TC.
