“…The MP2/AVTZ bond length of free CO 2 (1.1564 Å) is found in a very good agreement with the experimental value (1.16 Å) [29]. In Table 5, the two C-O distances (d 2 and d 3 ) and the O-C-O angle corresponding to the different complexes are shown and compared with the isolated molecule parameters.…”

In this research, a sample of expanded polystyrene (EPS) was isolated from a whole solid waste amount as raw material, the synthesis of polyamino styrene (PSNH 2 ) was done in a two-step process. Initially, it was carried out the nitration of PS to obtain polynitro styrene (PSNO 2 ) in 10.18% of nitration's efficiency. Afterward, the PSNO 2 was reduced under HCl/Sn conditions in order to obtain the PSNH 2 in 50% of yield taking into account the reduction of NO 2 groups from PSNO 2 . The raw material, intermediary and the final product were completely characterized by chemical analytical techniques. With the new material in hands, it was used as a solid support in the CO 2 capture process, showing an adsorption capacity of 1.05 mmol g −1 of PSNH 2 .

“…A two-armed macroinitiator was prepared by means of poly(St-co-4-chloromethyl styrene), and it had been copolymerized with isobornyl acrylate via ATRP [3]. The modifications of poly(4-chloromethyl styrene) were carried out using PS-imidazole, PS-diethanolamine, PS-piperazine, and PS-dimethylamine [8]. The polystyrene-based terpyridine polymer was prepared from 4-chloromethyl styrene [9].…”

4-Diethanolaminomethyl styrene (DEAMSt) monomer was prepared by the modification of 4-chloromethyl styrene with diethanolamine. The copolymers in different combinations (0.11, 0.19, and 0.30 by mole) of DEAMSt and methyl methacrylate (MMA) were prepared by free radical polymerization method at 60°C in the presence of 1,4-dioxane and AIBN as initiator. The structures of DEAMSt and DEAMSt-MMA copolymer were characterized by FT-IR and 1H-NMR. The glass transition temperature (Tg) of the copolymers was measured by DSC. Thermal decomposition behavior of the copolymers was investigated by TGA. The average molecular weights of the copolymers were determined by GPC. The dye uptaking properties of the copolymers were investigated using bromocresol green. Then, the dielectric constant, dielectric loss factor, and conductivity of copolymers were investigated as a function of temperature and frequency. The activation energies (Ea) of the copolymers were determined by impedance analyzer.
