Abstract
For the formation of poly(2-ethylhexyl-acrylate) polymer, the suspension polymerization was used with ultrasonic sonication. In the preparation of poly(2-ethylhexyl-acrylate) polymer, 2-ethylhexylacrylate as the starting material; ethyleneglycol dimethacrylate as the cross-linker; benzoylperoxide as the initiator; and gelatine were used. The oil-absorption capacity of the prepared poly(2-ethylhexylacrylate) polymer was measured at $20^{\circ}C$. It was shown that the oil-absorption capacity of poly(2-ethylhexylacrylate) polymer depended on the property of ultrasonic waves: the optimum sonication time and intensity of ultrasonic waves were 10 min and 675 W, respectively. The oil-absorption capacity, in the increasing order, was kerosene, bunker fuel oil B, bunker fuel oil A and crude oil. The oil-absorption capacity of these oils was saturated within 60 min at $20^{\circ}C$.
출발물질로서 2-ethylhexylacrylate, 가교성단량체로서 ethyleneglycoldimetha-crylate, 개시체로서 benzoylperoxide 및 현탁제로서 gelatine을 이용한 현탁중합을 통하여 poly(2-ethylhexylacrylate)를 얻었고 또한 $20^{\circ}C$에서 이들 중합체들의 흡유능력을 측정하였다. Poly(2-ethylhexylacrylate)의 흡유능력은 초음파의 조사시간과 조사강도에 크게 의존함을 알 수 있었고, 최적의 제조조건은 초음파 조사시간 10 min, 조사강도 675 W 이었고, 흡유능력은 등유, 중유, 원유의 순이었다. 또한 대부분의 기름은 60 min 이내에 포화흡유능력을 보였다.
