Abstract

Abstract An innovative method based on thermogravimetric analysis combined with gas chromatography and mass spectrometry, TGA–IST16–GC–MS, is developed for measuring the comonomer type and the comonomer content in a series of linear low‐density polyethylenes (LLDPE). LLDPE such as copolymers of ethylene and octene or ethylene and hexene are synthetized using the Et(Ind)2ZrCl2 zirconium‐metallocene catalyst. Their characterization with TGA‐IST16‐GC‐MS system is compared to one of the polyethylenes prepared under similar conditions and used as reference. TGA‐IST16‐GC‐MS allows discriminating the comonomer type (hexene or octene) and content. Combining the versatility of thermal analysis and the accuracy and sensitivity of mass spectrometry, this original method proves to be very useful for routine characterization of LLDPE. It has the advantage of being quicker and more easily performed that traditional means of obtaining copolymer compositions such as nuclear magnetic resonance, or through separation techniques such as temperature rising elution fractionation (TREF).

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • TGA-IST16-GC-MS was designed to determine the comonomer form and quality in a sequence of linear low-density polyethylene (LLDPE).

    “For example, TGA-IST16-GC-MS was designed to determine the comonomer form and quality in a sequence of liner low-density polyethylene (LLDPE).”
  • TGA-IST16-GC-MS is faster and easier to conduct than conventional methods of extracting copolymer compositions, such as nuclear magnetic resonance or temperature-escalating elution fractionation (TREF).

    “It is faster and easier to conduct than conventional methods of extracting copolymer compositions, such as nuclear magnetic resonance or temperature-escalating elution fractionation (TREF) [76].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
