Abstract:
A method and apparatus for chromatography of a polyolefin polymer by flowing a solution of the polyolefin polymer through liquid flowing through a graphitic carbon liquid chromatography stationary phase. The method can be used to determine the monomer to comonomer ratio of a polyolefin copolymer such as a copolymer of ethylene and 1-octene or a copolymer of propylene and ethylene.
