Crosslinking of reactive α‐olefins and maleic anhydride copolymers as oil sorbers

Abstract

Octene (OC) and tetradecene (TD) monomers were copolymerized with maleic anhydride (MA) with a low conversion (<10% conversion) to determine their reactivity ratios. The monomers were copolymerized with different molar percentages of MA and OC or TD (90/10, 70/30, 50/50, and 10/90) with benzoyl peroxide as an initiator to produce MA/a-olefin copolymers of different compositions. Fourier transform infrared was used to determine the copolymer compositions. The monomer reactivity ratios of the MA/OC and MA/TD copolymers were determined with the Fineman-Ross and Kelen-Tudos methods. Crosslinked MA/TD and MA/OC (50 : 50 mol/ mol) copolymers were prepared by the condensation of the prepared linear copolymers with different glycols. The crosslinked copolymers were evaluated for oil absorbency applications. The effects of the glycol type, composition, crosslinker weight percentage, and type of oil on the swelling properties of the crosslinked polymers were studied with oil absorption tests. The swelling parameters, such as the maximum oil absorbency, characteristic oil absorbency, characteristic swelling time, and swelling rate constant, 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.…”

“…Авторы [33] сополимеризовали мономеры октена (ОК) и тетрадецена (ТД) с малеиновым ангидридом (МА) при низкой конверсии (менее 10%). Мономеры сополимеризовали с различ-ными мольными процентами МА и ОК или ТД (90/10, 70/30, 50/50 и 10/90) с бензоилпероксидом в качестве инициатора для получения сополиме-ров разных составов.…”

Synthesis and swelling properties of new crosslinked polyorthocarbonates

“…Absorbent materials are attractive for oil and organic solvent removal. There are several reports in the literature describing the synthesis and swelling properties of polymers for oil or organic solvent cleanup 12–19. To be a good absorbing material, a sorbent should have hydrophobicty and oleophilicity, a high and fast uptake capacity, and reusability.…”
