Characterization of AN-SBR/Silica compound with acrylonitrile as a polar group in SBR

Macromolecular Research, 2012
In this study, acrylonitrile-styrene-butadiene rubber (AN-SBR), in which polar monomer acrylonitrile was introduced to emulsion styrene-butadiene rubber (SBR) as the 3rd monomer, was applied to silica compound to examine the various properties that are required for tire tread compound. The mechanical properties of the AN-SBR compounds, the modulus, and

Study of stress-strain characteristics of SBR and blended NR/SBR rubber

Czechoslovak Journal of Physics, 1995
The effect of temperature and carbon black (CB) on the mechanical characteristics of styrene-butadine rubber (SBR) and natural rubber (NR) was studied at various temperatures. The relation obtained between true stress and true strain for both types of rubber showed three regions at room temperature and two regions at high temperature.

Radical SBr: A challenge to spectroscopists?

The Journal of Chemical Physics, 2006
A theoretical description of the electronic states of the SBr radical at a high level of correlation effects treatment is presented for the first time. Most of its potential energy curves have a repulsive nature, but a set of bound Π2 states should provide a means for the experimental characterization of this species.

Studies on Blended Polymers. VIII. Blending of Carboxy SBR and Vinylpyridine SBR

Rubber Chemistry and Technology, 1969
Abstract Blends of carboxy-SBR and vinylpyridine-SBR, in which interactions were expected to occur between the two types of polymer molecules, were prepared by different blending methods and with different vulcanizing systems, and the variation of their properties with varying mixing ratio was studied.

Distribution of Carbon Black in SBR

Rubber Chemistry and Technology, 1977
Abstract The interparticle distance between black aggregates in rubber was estimated by Fraunhofer diffraction with the mask of an electron micrograph of filled rubber. Up to 40 phr, the distribution of interpartiele distance has a sharp peak centered at 8000 A˚ with 20 phr and at 7000 A˚ with 40 phr.

Influence of oil content and SBR type on blowout behaviors of SBR composites

Journal of Industrial and Engineering Chemistry, 2009
Abstract Blowout behaviors of carbon black-reinforced SBR composites were studied using a microwave oven and influence of the oil content and the SBR type on the blowout behaviors was investigated. Morphology of the interior of the sample before exploding was observed and change of the crosslink density was also measured.

The Oxidative Hardening of SBR

Rubber Chemistry and Technology, 1972
Abstract During aging, SBR hardens. This hardening can be followed by swelling volume, hardness, and modulus measurements. Crosslink properties are important in determining the amount of oxidative hardening. The quantity of Sx-type sulfur in the R−S−Sx−S−R polysulfide crosslinks correlates well with the extent of hardening.

Aging of SBR. II

Journal of Applied Polymer Science, 1966
AbstractComparison of aging of a sulfur vulcanizate with a control having stable crosslinks, shows that oxygen affects reactions of the crosslink as well as of the hydrocarbon. Crosslink scission is inhibited. Results are in agreement with an earlier Suggestion that new crosslinking is enhanced by oxygen, although less than observed for natural rubber.
