Abstract

A new oil absorbent composed of polymer material, which could absorb various kinds of organic solvents and oil and whose absorbed amount of organic solvents and oil was high, was developed. For this purpose, 282 μm of polymer particles synthesized by suspension copolymerization of 2-hydroxyethyl acrylate and various cross linkers was reacted with hydrophobic fatty acid chloride. Produced particles could absorb various kinds of organic solvents and oils. Monodisperse polymer particles synthesized by seed copolymerization using 2,2′-azobis[N-(2-propenyl)-2-methylpropionamide] had azo group incorporated polymer network. Using this azo group as an initiator, graft chain composed of 2-hydroxyethyl acrylate and hydrophobic fatty acid chloride was introduced in the particles. The amount of organic solvent or oil of produced particles was 1.2–3.7 times of that of particle synthesized from suspension polymerization.
