This paper discusses a novel approach that may provide a complete solution to combating oil spills. The technology is centered on a cross-linked polyolefin terpolymer (x-OS-DVB), containing 1-octene, styrene, and divinylbenzene units. Some terpolymers show rapid oil absorption and swelling to reach a capacity >50 times of their weight. The combination of selective oil absorption (without water) and tough mechanical strength offers buoyancy, stability, and easy recovery on water surfaces. The recovered oil-swelled gel is suitable for regular oil refining processes (an economic, no waste, and no pollutant approach). The bulk side chains in x-OS-DVB reduce the ceiling temperature for depolymerization and result in zero heating residue at 450o C. Furthermore, polyolefins are the most inexpensive polymeric material, with a large production capability around the world. Overall, this cost-effective new polyolefin oil-SAP technology shall dramatically reduce the environmental impacts from oil spills and help recover one of our most precious natural resources.
