1,3-Butadiene (BD), which is used to make styrene-butadiene rubber, is a potent carcinogen in mice and a probable carcinogen, associated with leukemia, in humans. We have previously used HPRT mutation as a biomarker to evaluate exposures to BD in a monomer production plant. We now report on a study of 49 workers in a styrene-butadiene rubber plant in which we used the concentration of the BD me...

In the article, it was determined that furan oligomer added to composition causes additional structuring in process of vulcanization, and as a result, density hardness vulcanization network composite increases, value relative length decreases. It shown optimal amount oligomers rubber compounds is equal 10 weight units per 100 rubber. With inclusion secondary product acetylene production elastom...

This theoretical article investigates an industrial emulsion copolymerization of acrylonitrile (A) and butadiene (B), for the production of grades BJLT and AJLT of a nitrile rubber (NBR). The simulated process involves a train of eight continuous stirred-tank reactors operating at 10 ◦C. The product quality is determined by its molecular structure (average copolymer composition, average molecul...

In this study, a chemical dissolution treatment was used to recover rubber and carbon black (CB) from truck tire scrap, with gas oil acting as the solvent 4-Hydroxy-TEMPO catalyst for reactions. Montmorillonite clay separate solution CB other non-dissolved additives. The recovered were characterized together original scrap sample by XRD, SEM, BET thermal analysis, well FTIR 1H NMR spectral anal...

Agricultural workers rely on chemically protective gloves for protection from dermal exposure to insecticides. In Australia the most widely used gloves are manufactured from polyvinyl chloride or nitrile butadiene rubber. During insecticide application splashes and spills frequently occur on the external surfaces of gloves which may compromise the integrity of the membrane. Interaction of two o...

Toughening of polyamide 6 (PA6)/ Nanoclay (NC) nanocomposites with styrene-ethylene/butadiene-styrene copolymer (SEBS) using maleated styrene-ethylene/butadiene-styrene copolymer (mSEBS)/ as a compatibilizer were investigated by blending them in a co-rotating twin-screw extruder. Response surface method of experimental design was used for optimizing the material and processing parameters. Effec...

Kompleks ortamlarda asphalt kaplamaların performansını garanti etmek için styrene- butadiene- styrene (SBS), butadiene rubber (SBR), crumb (CR), and polyphosphoric acid (PPA) gibi bazı malzemeler bitüm modifikasyonunda kullanılmıştır. Modifikasyon yöntemleri sırasında, geleneksel asfalt bağlayıcıyı geliştirmek veya desteklemek alternatif katkılar Modifiye üretilmesinde en çok kullanılan polimer...

In road paving industry, asphalt emulsion is used for cold mix application such as chip seal, slurry seal, microsurfacing, cold recycled mixture and etc. Asphalt emulsion has several advantages compared to normal asphalt such as eco-friendly, easy to handle at ambient temperature and energy saving material because it does not need any heating process in its application. The history of asphalt e...

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...
