The effects of SBR/NBRr blends on properties of such fourier transform infrared (FT-IR) and morphology properties were carried out. FT-IR analysis showed that SBR/NBRr R05 blended with the smallest size NBRr (S1) and showed most intense amine absorption at 1535 cm-1. The intensity decreased...

Thermogravimetry was used to quantify the real content of NR and SBR in the blends through the ratio between the intensity of the peaks in the derivative curve (DTG). The FT-IR analytical bands chosen at MIR region were 885 cm -1 (A 1 ) for NR and 699 cm -1 (A 2 ) for SBR. ...

The thermo-oxidation of unfilled styrene-butadiene rubber (SBR) was examined by Fourier transform infrared spectroscopy and differential scanning examined by Fourier transform infrared spectroscopy and differential scanning calorimetry (DSC). The process was found to follow an auto-oxidative reaction ...
The base resir is a mixture of aqueous poly (vinyl alcohol) (PVA) solution, emulsion of styrene-butadiene rubber (SBR) an(l filler. The crosslinking agent is usually polymeric methylene bis (4-phenylisocyanate), 4,4'-pMDI. WPI have been used widely, because it cures very rapidly in ...
The species present in the vapours of CsBr and CsI have been isolated in krypton and xenon matrices and were investigated by FT-IR spectroscopy in the range of 180–30 cm −1. The recorded spectra revealed the presence of substantial amounts of dimer beside the alkali halide monomers. The...
DMSO , SO 2 , COS, CH 3 SBr andCH 3 SO 2 Br were identified as the main sulphur containing products of the oxidation of DMS by Br atoms. From the reaction between DMSO and Br atoms, DMSO 2 and CH 3 SO 2 Br were the only sulphur containing products thatwere identified. DMSO , ...
The major sulfur products observed included SO2, CH3SBr, and DMSO. The kinetic observations in combination with the product studies under the conditions employed are consistent with rapid addition of Br atoms to DMS forming an adduct that mainly re-forms reactants but can also decompose u...
SBRcrosslink structureThis paper describes experimental work where the mechanical behaviour of relatively dry, solid poly(acrylic acid) films at room temperature was correlated with changes in hydrogen-bonding in the polymer. Hydrogen-bonding between the carbonyl and the hydroxyl groups was followed by...
