Extending the mechanical lifetime of NBR (i.e., poly(acrylonitrile-co-butadiene)), a large-volume synthetic rubber, requires better understanding its structure–property relationships. We demonstrate that industrial-grade and uncross-linked can be mechanically rejuvenated physically aged due to an inhomogeneous distribution monomers along polymer chains. As opposed nonpolar SBR counterpart poly(...

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...

polymer application for the improvement and modification of the bitumen used in roads surfaces has expanded in recent decades. the roads engineers and constructors, therefore, have used the modified bitumen in asphalts helping in this way to increase roads and pavements service life and improving the durability of the roads and asphalts. the bitumen used in asphalt mixture constitutes only a lo...

The effects of two types silanes, which were bis (triethoxysilylpropyl) tetrasulfide (Te) and octyltriethoxysilane (Oc), on the extrusion properties styrene-butadiene rubber (SBR) /silica (Si) composite investigated from viewpoint bound rubber. surface roughness SBR extrudate slightly increased when adding Te, didn't increase Oc. On other hand, for SBR/Si composites was smooth, it hardly change...

The co-pyrolysis of various biomasses mixed with two types plastic waste was investigated in this study. Mixture M1 consisted 30% m/m styrene–butadiene rubber (SBR), 40% polyethylene terephthalate (PET), and polypropylene (PP). M2 PET, PP, acrylonitrile–butadiene–styrene copolymer (ABS). SBR, ABS, PP used study were from the automotive industry, while PET originated scrap bottles. Co-pyrolysis ...
