Santowhite powder

RPLC-UV-MB-MS (dual detection in series) with methane Cl mass spectra (m/z 200 to 1200) was first used for identification of AOs and UVAs [523,578] ng quantities of a nine-component additive mixture (BHT, Santowhite Powder, Topanol CA, Cyasorb UV531/5411, Irganox 1010/1076, Ionox 330, DSTDP) were detected... [Pg.513]

Some of recent papers by Ratner et al. [63, 64] revealed that there are significant differences in the surface chemistry of Biomer lots. The surface of some lots was dominated by poly(diisopropylaminoethyl methacrylate) (DPAEMA or DIPAM), a high molecular weight UV stabilizer, which was absent from some older lots [65]. Ratner et al. carried out comparative studies on in vitro enzymatic and oxidative degradation of two lots of Biomer, BSU 001 and BSP 067. Lot BSU 001 contains both DPAEMA and an antioxidant, Santowhite powder, while BSP 067 contains only the antioxidant. It was found that DPAEMA retarded the enzymatic degradation process, but accelerated oxidative degradation. [Pg.23]

Campbell and Wise [2] applied column chromatography to the determination of known phenolic antioxidants in polyethylene (PE). This method is applicable to the analysis of mixtures of Santowhite powder (4, 4"-butylidene-bis-(6- er -butyl-w-cresol) with BHT (2,6-di-ter -butyl-p-cresol) and mixtures of Santonox R (4, 4 -thio-bis-(6-fert-butyl-m-... [Pg.141]

Elution with chloroform removes BHT only as the first fraction. Continued elution of the column with solutions of 10% water in methanol removes Santowhite powder or Santonox R as a separate pure fraction, free from BHT. Additives can then be determined in the respective extracts after they have been diluted to a standard volume with solvent by ultraviolet (UV) spectroscopy. [Pg.142]

Fig. 10.7 shows the L2MS spectra of a pure antioxidant Santowhite powder (4,4 -butylidene-bis-6-(4-methyl-2- cr/-butylphenol) and the in situ spectrum of Santowhite powder in a POM injection molded bar. The Santowhite powder was present at only 0.1 wt%. The laser desorption was produced with an CO2 IR laser with power density of 6 x lO W/cm - at 10.6 p,m and laser photoionization was produced at UV 266 nm with a power density of 2 Mw cm . ... [Pg.462]
