Abstract
The invention provides methods for chromatography of a polyolefin polymer, comprising introducing a solution of the polyolefin polymer into a liquid flowing through a liquid chromatography stationary phase, the liquid chromatography stationary phase comprising graphitic carbon. The invention also provides an apparatus for polyolefin polymer chromatography, comprising a liquid chromatography stationary phase, the liquid chromatography stationary phase comprising graphitic carbon and at least one inert filler.
