- Crosslinked styrene–acrylate copolymers were synthesized and evaluated
by swelling properties for oil-absorbency application. The effect of various polymerization
conditions (crosslinking agent concentration, initiator concentration, monomer
concentration, and polymerization temperature) were studied through oil-absorption
tests using kerosene oil. The oil absorbency was influenced mainly by the degree of
crosslinking and the hydrophobicity of the copolymer units. The effect of moisture and
the types of acrylate were also investigated. The copolymer with a longer alkyl acrylate
had higher oil absorbency in the order of stearyl acrylate (SA) . lauryl acrylate (LA)
. 2-ethylhexyl acrylate (EHA). The oil absorbency of the lauryl methacrylate (LMA)
copolymer was higher than that of the LA copolymer.
