Abstract: A method to determine the weight percent of an “amorphous” fraction in an olefin-based polymer composition, comprising one or more olefin-based polymers; said method comprising the following steps: a) dissolving the olefin-based polymer composition in an organic solvent to form a polymer solution; b) injecting at least a portion of the polymer solution onto a support material, and wherein the support material has a Co-crystallization Index (CI) value from 0.70 to 1.20; c) cooling the support material at a rate greater than, or equal to, 0.2C/min; d) increasing the temperature of the support material to elute the polymers of the olefin-based polymer composition; e) generating a chromatogram; f) determining the peak area of the first elution from its lower integration limit to its upper integration limit; g) calculating the “amorphous” fraction” based on the following Equation A below: wt % “amorphous” fraction=PAamorphous/PAtotal×100 (Eqn. A); wherein PAamorp=peak area of the first elution, and PAtotal#191=total peak area of the polymers of the olefin-based polymer composition.

Abstract: A method increase of the Resolution Index (Rl) of a chromatogram generated from a polymer sample comprising at least two olefin-based polymers of different microstructures and/or at least two olefin-based polymer fractions of different microstructures. The method comprises separating the mixture on a low-porosity stationary phase and repeatedly cycling the sample-stationary phase through a series of cooling and heating stages with active eluent flow only during the cooling stages and during the last heating stage to elute the separated analytes off the column.
