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.

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.

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.

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.
