Abstract
A method of analyzing a multi-component polymer comprising: (a) dissolving an multi-component polymer having a primary monomer and primary comonomer to form a first volume (soluble portion of multi-component polymer); (b) injecting a portion of the first volume into a chromatographic column to get elution first slices, leaving a second volume behind; (c) filtering the second volume to isolate multi-component polymer solids; (d) dissolving solids to form solution third solution (insoluble portion of multi-component polymer); (e) injecting a portion of third solution into the chromatographic column to get elution second slices; (f) obtain infra-red spectra at wavelengths suitable for the primary monomer and the primary comonomer of first and second elution slices, separately; and (g) for each elution slice, separately calculate: (i) the different polymer components (soluble and insoluble); and (ii) the comonomer content of each component (soluble and insoluble).
