“…The bath temperature was steadily increased to 170°C and then held at 160 °C for 4 hours. Continuous mixing was used until the reactants were fully melted producing a pale brown material (Hyperbranched Polyester Polymer) (AL-Abayechi et al, 2020;Al-zuhairi, 2020;Al-Zuhairi et al, 2017;Higashihara et al, 2012;Ishida et al, 2000;Yue et al, 2013;Zhang et al, 2009).…”

“…According to many research, dendritic polymers have been used as rheology modifiers, curing agents, dispersion agents, compatibilizers, and processing aids (Diao et al, 2006;Mulkern and Tan, 2000;Tatiya et al, 2014;Wågberg et al, 2007;Yiyun et al, 2005). In recent years, several studies have been conducted for the preparation of hyperbranched polymers that have different functional groups with different properties (AL-Abayechi et al, 2020;Al.-Zuhair, 2020;Al-Zuhairi et al, 2017;Higashihara et al, 2012;Ishida et al, 2000;Yue et al, 2013;Zhang et al, 2009).…”

Compared to linear analogs, hyperbranched polymers (HBPs) have gotten much attention in the last decade because of their intrinsic globular topologies and distinctive features like low viscosity, high solubility, and a high degree of functionality. In this work, four types of hyperbranched polyester polymer HBPs have been synthesized using the A2+B3 polycondensation methodology. Firstly, the starting material B3 monomer (Pyrimidine-2,4,6-triol) has been synthesized using urea and malonic acid with the presence of sodium Na as the catalyst for the reaction. Secondly, four types of materials (tartaric acid TA, adipic acid AD, maleic acid MA, and phthalic anhydride PA) as A2 monomers were added to the starting material B3 monomer in an oil bath to prepare the four types of HBP. The chemical structure of HBPs was characterized by FTIR, and 1H-NMR. The molecular weight of the prepared HBPs was characterized by gel permeation chromatography GPC, and thermal properties were characterized by differential scanning calorimetry DSC and thermal gravimetric analysis TGA. FTIR results showed that there are new bands, such as C-O-C between A2 and B3 monomers, as indicated by 1H-NMR. In addition, GPC shows that the prepared polymers have a narrow molecular weight distribution with good thermal stability, as indicated by DSC and TGA.

The increasing demand for searching highly efficient and robust technologies in the context of sustainable energy production totally rely onto the cost-effective energy efficient production technologies. Solar power technology in this regard will perceived to be extensively employed in a variety of ways in the future ahead, in terms of the combustion of petroleumbased pollutants, CO 2 reduction, heterogeneous photocatalysis, as well as the formation of unlimited and sustainable hydrogen gas production. Semiconductor-based photocatalysis is regarded as potentially sustainable solution in this context. g-C 3 N 4 is classified as non-metallic semiconductor to overcome this energy demand and enviromental challenges, because of its superior electronic configuration, which has a median band energy of around 2.7 eV, strong photocatalytic stability, and higher light performance. The photocatalytic performance of g-C 3 N 4 is perceived to be inadequate, owing to its small surface area along with high rate of charge [a] A
