Synthesis and properties of oil absorption resins filled with polybutadiene

Abstract

Polybutadiene (PB) is used to fill an oil absorption resin as a physical crosslinker to construct a kind of 3-dimensional network with a high degree crosslinking and low crosslink density. A series of acrylic resin particles with various compositions are prepared by suspension polymerization, using benzoyl peroxide (BPO) as an initiator and ethylene glycol dimethacrylate (EGDMA) as a chemical crosslinker. The effects of the polymerization temperature, initiator concentration, monomer feed ratio, and chemical and physical crosslinker concentrations on the oil absorbency and gel fraction (degree of crosslinking) are studied. The recipe and operation conditions are optimized as follows: a mass ratio of 3:1 for styrene (St)/dodecyl methacrylate or St/butyl acrylate, 0.5 wt % BPO, and 80°C for 7-8 h. The effect of the physical crosslinker (PB) concentration is complex. The oil absorbency increases with increasing PB at lower EGDMA concentrations. However, under this same condition, particles cannot be formed if the PB concentration is higher than a certain value. By contrast, there is an optimum PB concentration when the EGDMA concentration is higher. The oil absorption speed is also investigated. The presence of PB can speed up absorption.

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

“…The monomer feed ratio affects the hydrophobicity and the effective volume of the cross-linking network, and therefore affects its oil absorption process and oil absorbency (Jang & Kim, 2000b;Shan et al, 2003a;Zhou & Cho, 2002). A series of poly(ODA-co-BA) oil-absorbents with varied monomer feed ratios (ODA/BA = 80/20,70/30,60/40,50/50,40/60,30/70,20/80,mol/mol) were prepared with all other variables unchanged.…”

“…Among them, oil-absorbent is widely regarded as the best cleanup material for absorbing oils because of the relatively fast oil absorption rate, large oil absorbency, and good absorption selectivity of oil over water. 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.…”

Facile fabrication of porous oil-absorbent microspheres with high oil absorbency and fast oil absorption speed

“…The fully swollen sample was collected by passing through stainless-steel mesh. The oil absorbency value was obtained from eqn (1) in the same way as described above.…”

“…[1][2][3][4][5][6] Therefore, it is necessary to prepare highly efficient cleanup materials to remove these contaminants. [3] Various oil absorption materials have been used to absorb the pollutants, [7] among which the oil absorption polymers exhibit high oil absorbency, excellent oil retention, and good absorption selectivity toward oils over water, and thus have attract evergrowing attention.…”

Preparation of a biodegradable oil absorber and its biodegradation

“…Shan et al [10] synthesized an oil absorption resin filled with polybutadiene and investigated its properties. Shin et al [7] synthesized an oil absorption resin using lauryl acrylate, and reported that its oil absorption capacity increased in the order of: aromatic compound [ saturated hydrocarbon [ water.…”
