ABSTRACT:
A polyurethane particulate liquid absorbent, optionally containing microspheres, and a process for its preparation. The absorbent is suitable for use in cleaning up spilled liquids ranging from mobile ones, such as gasoline, to visconsones, such as crude oil. The absorbent and absorbed liquid are readily separated by a centrifugation step, thus providing recovered liquid, and liquid-free absorbent for re-use.
