Crosslinked poly(octadecene‐alt‐maleic anhydride) copolymers as crude oil sorbers

Abstract

Crosslinked octadecene (OD) and maleic anhydride (MA) copolymer MA/OD (50 : 50 mol ratios) was prepared by condensation of the prepared linear copolymer with different glycols. Ethylene glycol and polyethylene glycols having different molecular weights were used as crosslinking agents. The crosslinked copolymers were evaluated for oil-absorbency application. The effect of glycol type, composition; crosslinker wt % and type of oil on swelling properties of crosslinked polymers were studied through the oil absorption tests. The swelling parameters, such as the maximum oil absorbency (Q max ), characteristic oil sorbency (Q), characteristic swelling time (T), and swelling rate constant (k), were evaluated for the synthesized sorbers.

β-Cyclodextrin-based oil-absorbents: Preparation, high oil absorbency and reusability

“…For some oil-absorbents in literature, soluble fraction (SF) (Atta et al, , 2006(Atta et al, , 2007a(Atta et al, , 2007b or gel fraction (GF) (Zhou & Cho, 2002) was measured to investigate the cross-linking of the absorbent networks. In the present study, cross-link degree (D) of the oil-absorbents was determined in a similar way to characterize the oil-absorbents.…”

“…Oil absorption test 2.6.1. Oil absorbency The oil absorbency (Q) was determined by the method reported in literature (Atta et al, , 2006(Atta et al, , 2007a(Atta et al, , 2007bKulawardana & Neckers, 2010;Wu & Zhou, 2009b;Zhou & Cho, 2001. A quantity of about 0.02 g of dried oil-absorbent sample with known weight (m 3 ) was put into a filter bag and immersed in four different oils (tetrachloromethane, chloroform, xylene, and toluene) at room temperature.…”

“…Many researchers have made significant contributions towards the progress on the synthesis of oil-absorbent (Farag & El-Saeed, 2008;Jang & Kim, 2000a, 2000bKim, Chung, Ha, Kim, & Cho, 1999;Medeiros, Oliveira, Sansiviero, Araujo, & Lago, 2010;Shan, Xu, Weng, & Huang, 2003a, 2003bShimizu, Koshiro, Yamada, & Tada, 1997;Zhou & Chuai, 2010). Atta and coworkers reported some oil-absorbents based on polyisobutylene/octadecyl acrylate copolymers (Atta, El-Ghazawy, Farag, & Abdel-Azim, 2006), cinnamoyloxyethyl methacrylates/isooctyl acrylate (Atta, El-Ghazawy, Farag, ElKafrawy, & Abdel-Azim, 2005), and reactive ␣-olefins/maleic anhydride (Atta & Arndt, 2005;Atta, El-Hamouly, Sabagh, Al, & Gabr, 2007a, 2007b. Zhou et al prepared 4-tert-butylstyrene-EPDM-divinylbenzene graft terpolymer and investigated the oil absorption properties (Wu & Zhou, 2009a, 2009bZhou & Cho, 2001, 2003.…”

Preparation of Water Based Polymeric Binders for Paper Surface Coating

“…The presence of two absorption peaks at 1810 and 1770 cm −1 , assigned for the carbonyl of the anhydride group, confirms the presence of MA in the structure of the produced copolymers. The appearance of these bands indicates that the anhydride groups were not hydrolyzed during the copolymerization of AA with MA [19]. It was also observed that, the absorption bands at 3100 and 1600 cm −1 , assigned to =CH and C=C, disappeared in all spectra of MA/AA copolymers and confirm the complete polymerization of AA and MA monomers.…”

“…Сшитые сополимеры МА/ ТД и МА/ОК (50:50 моль/моль) получали кон-денсацией линейных сополимеров с различными гликолями. Те же авторы [34] получили сшитый сополимер октадецена (ОД) и малеинового анги-дрида МА/ОД (50:50 моль/моль) конденсацией соответствующего линейного сополимера с различными гликолями (в качестве сшивающих агентов использовали этиленгликоль и полиэти-ленгликоли с разной молекулярной массой). Изу-чали влияние типа гликоля, состава, содержания сшивающего агента и типа нефти на набухание в ней сшитых сополимеров.…”
