Abstract
A polymer composition for use in the removal and recovery of oil slicks or spills floating on the surfaces of bodies of water or present on land, such as beaches comprising a foam of a blend of polyethylene and an ethylene-alkyl acrylate copolymer and a process for using such foams in the selective removal of oil from fresh water or salt water and the recovery of the absorbed oils from the foams is disclosed. The polymer composition is also for use in other applications in which absorption of liquids is desired.
