The functionalization of elastomers by phosphonate groups remains relatively unexplored considering the great potential these polymers would represent for applications. In this paper, thiol-functional oligophosphonates were designed and coupled a thiol-ene reaction to styrene-butadiene rubber (SBR). We adopted RAFT methodology with dimethyl vinylphosphonate (DMVP) high-temperature thermolysable...

We have measured the friction force acting on a rubber block slid on a concrete surface. We used both unfilled and filled (with carbon black) styrene butadiene (SB) rubber and have varied the temperature from -10 °C to 100 °C and the sliding velocity from 1 μm/s to 1000 μm/s. We find that the experimental data at different temperatures can be shifted into a smooth master-curve, using the temper...

This study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. Starch-based SBR1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (Plastograph Brabender).The content in starch was varied from 0 to 50 phr. The effect of starch content on the rheological behavior was ev...

Advanced experimental techniques in terms of situ dilatometry and X-ray microtomography as well microscopy have been used to investigate cavitation unfilled carbon black reinforced styrene-butadiene rubber vulcanizates. The work introduces into the features multiaxial deformation damage behavior characterized by formation growth internal defects – so-called cavities. Experimental evidence indic...

The aim of the study is to effect gas pyrolysis resin on properties elastomeric composite materials. It has been established that in presence it thiuram vulcanizing system, relative rate vulcanization styrene-butadiene rubber increases, time reach optimum decreases, but degree proportional maximum torque, and when using a sulfur activates process, which facilitated by its composition active fun...

Rubber-filler composites are a key component in the manufacture of tyres. The filler provides mechanical reinforcement and additional wear resistance to the rubber, but it in turn introduces non-linear mechanical behaviour to the material which most likely arises from interactions between the filler particles, mediated by the rubber matrix. While various studies have been made on the bulk mecha...
