Swelling and network parameters of high oil‐absorptive network based on 1‐octene and isodecyl acrylate copolymers

Abstract

Crosslinked 1-octene-isodecyl acrylate copolymers were synthesized and evaluated for oil-absorbency applications. The copolymer was crosslinked at different concentrations of ethylene glycol diacrylate (EGDA) and EG dimethacrylate (EGDMA) crosslinkers via catalytic initiation or by electron-beam irradiation at a dose rate 80 kGy. The concentration of both crosslinkers was varied from 0.5 to 2%. The effects of the crosslinking conditions such as crosslinker concentration, method of polymerization and monomer concentrations on the conversion and gel fraction were examined through oil-absorption tests using petroleum crude oil. It was found that the oil absorbency was influenced mainly by the degree of crosslinking and the hydrophobicity of the copolymer units. The final equilibrium oil content, volume fraction of the polymer, and swelling capacity were determined at 298 K. The effective crosslinking density, average molecular weight between the crosslinks, and polymer-toluene interaction parameter were determined from stress-strain measurements. The crosslinking efficiencies of EGDA and EGDMA toward copolymers were determined.

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

“…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.…”

Crystal network for edible oil organogels: Possibilities and limitations of the fatty acid and fatty alcohol systems

“…Personal care products are to deliver functionality whilst being structured, while the crude oil industry just tries to avoid that the oil gets structured (Visintin, Lapasin, Vignati, Dántona, & Lockhart, 2005;Stachowiak, Viguié, Grolier, & Rogalski, 2005; Buenrostro-Gonzalez, Lira-Galeana, Gil-Villegas, & Wu, 2004). A recent review on oil structuring is presented by Pernetti, van Malssen, Flö ter, and Bot (2007 There are several schemes that can be applied to structure oil, such as the application of polymers (Atta & Arndt, 2005), surfactant systems (Angelico et al, 2005), or low-molecular weight gelators (Ojijo et al, 2004a(Ojijo et al, , 2004bGandolfo et al, 2004;Realdon et al, 2001), in order to replace classical structuring components. Fats and oils show a very strong intersolubility between TAGs, mono-and diacylglycerols, as well as free fatty acids in the liquid or in the solid state.…”

Oil‐absorptive polymeric networks based on dispersed oleophilized nanolayers of laponite within ethylene–propylene–diene monomer vulcanizates

“…Atta and coworkers 8,9 synthesized oil-absorptive networks based on 1-octene and isodecyl acrylate copolymers or pairs of 1-docosanylacrylate, cinnamoyloxy ethyl methacrylate, and methyl methacrylate in the presence of an initiator and 1,1,1-trimethylolpropane triacrylate as a crosslinker, and these proved to be highly efficient oil sorbents.…”
