Evaluation of Moisture Susceptibility for Modified Open Graded Friction Course Mixes Used Styrene Butadiene Styrene

Butadiene and Styrene Risks

The control of cell proliferation by gastrin has been investigated in a rat pancreatic tumour cell line, AR4-2J. Exogenous gastrin, 10-12 to 10-8 M, stimulated cell growth of thymidine-synchronised AR4-2J cells cultured over 48 h in serum-free medium. Cell lysates of AR4-2J cells contained an average of 4.5 and 3.5 pg gastrin per 106 cells, when grown in serum-supplemented or serum-free media, ...

Styrene-butadiene-styrene Tri-block Copolymers Modified with Polyhedral Oligomeric Silsesquioxanes

Performance Analysis of Styrene Butadiene Rubber-Latex on Cement Concrete Mixes

To improve the performance of concrete, polymers are mixed with concrete. It has been observed that polymer-modified concrete (PMC) is more durable than conventional concrete due to superior strength and high durability. In this research, effect of Styrene-Butadiene Rubber (SBR) latex on compressive strength and flexural strength of concrete has been studied and also the optimum polymer (SBR-La...

Synthesis and Characterisation of Styrene Butadiene Styrene Based Grafted Copolymers for Use in Potential Biomedical Applications

In the annals of history the evolution of the synthetic rubber industry can be traced to the early 1930s where the first emulsion polymerised styrene butadiene rubber known as Buna S was prepared by I. G. Farbenindustrie in Germany. But it was not until the US Government in 1940 established the Rubber Reserve Company, a stockpile of natural rubber and the development of a synthetic rubber progr...

Mechanical, Electrical and Electro-Mechanical Properties of Thermoplastic Elastomer Styrene-Butadiene-Styrene/Multiwall Carbon Nanotubes Composites

Composites of styrene-butadiene-styrene (SBS) block copolymer with multiwall carbon nanotubes (MWCNT) were processed by solution casting in order to investigate the influence of filler content, the different ratio of styrene/butadiene in the copolymer and the architecture of the SBS matrix on the electrical, mechanical and electro-mechanical properties of the composites. It was found that fille...
