characterized in that in component C the ratio of the integrated peak area of the FTIR spectrum in the wavenumber range 1630 cm-1 to 1560 cm-1 to the integrated peak area of the FTIR spectrum in the wavenumber range 1520 cm-1 to 1350 cm-1 is in the range of (80-160)路10-3, to...
wherein ppm OH is the amount of hydroxyl end groups in ppm and Mn is the number averaged molecular weight based on polycarbonate standards in Daltons. The ppm OH can be determined by Fourier Transform Infrared Spectroscopy (FTIR), for example, on a Perkin Elmer FTIR Spectrum One Device by ...
(PC) modified with combinations of earth metal salts of inorganic sulfur, potassium perfluorobutane sulfonate (Rimar); non-halogenated flame retardant additives, potassium diphenyl sulfone-3-Sulfonate (KSS); and block co-polymers-polytetrafluoroethylene encapsulated with styrene acrylonitrile resin (T-SAN...
a ratio of an integrated peak area of an FTIR spectrum in a wavenumber range of 1630 cm-1 to 1560 cm-1 to an integrated peak area of an FTIR spectrum in a wavenumber range of 1520 cm-1 to 1350 cm-1 is in a range from (80-160)路103.\n;A process for producing a moulding mater...
While the FTIR spectroscopy shows that both polymers are present in the bulk, the Raman microscopy proves the presence of polymer blend particles (i.e., PBT and PC are present in a single particle). These results are complemented by the SEM analyses of the stained samples and polarized light...
FTIR (Model Spectrum One/BX, PerkinElmer Inc., Waltham, MA, USA) was used to characterize the chemical structure and the changes induced due to the different types of solvents used during the preparation of the membranes. A thermogravimetric analyzer (TGA, STA6000, PerkinElmer Inc.) was ...
