In this article, we show the benefits of simultaneously coupling a GC/MS and an FTIR spectrometer to the TGA, using polypropylene as an example. Introduction Instrument combinations involving a thermogravimetric analyzer (TGA) coupled to a mass spectrometer (MS), a Fourier-transform infrared ...
FTIR spectra, Raman spectra and wide-angle X-ray scattering (WAXS) patterns of polypropylene, cyclic olefin copolymer and its blends were recorded in solid phases and carried out qualitative and quantitative analysis in detail. The characteristic absorption peaks of PP, COC and PP/COC blends were...

An article in the September issue ofPlastics Engineeringillustrates an example where polymer blend analysis using FTIR may be useful. It describes the efforts of a company experimenting with making eyeglass frames from a variety of recycled plastics. The company is blending polypropylene with polyethylen...
Layer-by-layer technique, FTIR external spectroscopy, textile material, polypropylene, nonwovenOppositely-charged polyelectrolytes such poly(acrylic acid) and poly(allylamine hydrochloride) have been deposited on a polypropylene nonwoven by the layer-by-layer technique. The complex formation of this ...
当温度为265℃时聚丙烯在热氧降解过程中产生的羰基含量最高,为(11.82±1.52)×10—5 mol/g;当样品温度超过265℃,羰基的分解速率大于其生成速率,使得羰基含量呈下降趋势.%The polystyrene(PS)was employed as inter standard,the variation of carbonyl group content in polypropylene(PP)matrix during thermal-...

Other studies have also shown that PE, polypropylene (PP), PET and PES, PVC, polystyrene (PS), PU and PA are resistant to WPO, with no change observed to MP size and spectra before and after treatment. Together these polymers account for 92% of global plastic demand [22,55,56,58,63...
FTIR spectral scan alone may not identify the type of Nylon, Pebex, or Polyester, identify a Polypropylene or Acetal as a homopolymer or copolymer, or determine whether a Polyethylene is a high density or low density material. Further identification using other analytical techniques is necessary. ...
