摘要：Crosslinked copolymers for oil absorption were synthesized by copolymerizing styrene (St) with lauryl acrylate (LA), with ethylene glycol dimethacrylate as crosslinking agent. Suspension polymerization was conducted using benzoyl peroxide as initiator. The crosslinking reaction mechanism and the structure of the composite were characterized by FT-IR analysis. Effects of different polymerization conditions were studied through oil absorption tests. The oil absorbency was influenced mainly by the degree of crosslinking and the LA/St ratio. Optimal oil absorbency was obtained for St/LA = 1. The absorbency of copolymers was higher for the aromatic series by the affinity investigation toward different organic solutions.
