1. Evaluation of silanes in SBR 1502 / Telinne Monspessulana flour composites
Abstract A comparative study was performed on the effect of the addition of silane coupling agents (SCA), vinyltrimethoxysilane (VTMS) and 3-aminopropyltriethoxysilane (APTES) to a mixture of styrene butadiene rubber SBR1502 with Telinne Monspessulana flour (TMF). SCA was directly added into the mixture using untreated and mercerized TMF. Also, TMF and SBR15

2. Evaluation of mechanical and rheological properties of butadiene-styrene(SBR) compounds filled with elastomeric wastes from useless tires / Avaliação das propriedades mecânicas e reológicas de composições de butadieno-estireno (SBR) com resíduos elastoméricos de pneus inservíveis
Currently, the great appeal about the ambiental questions has forced much more companies and industries around the world to search ecological alternatives to their activities. However, the environmental sustainability it is not a task only for the factories. The consumption society must be able to choice products obtained by cleaner technologies and easily d

3. Obtenção e caracterização de artefatos produzidos com resíduos elastoméricos vulcanizados
The aim of this study was to incorporate styrene-butadiene rubber (SBR) industrial scraps into a base formulation of identical composition used in the fabrication process of extruded profiles. Technical and environmental performance of the developed composites was evaluated. The scraps were collected and ground under ambient conditions. The powder obtained,

4. Evaluation of the influence of the polymer-filler interaction on compounds based on epoxidized elastomeric matrix and precipitated silica
The introduction of epoxy groups into the main chain of elastomers has emerged as a promising alternative, considering the monitoring of polymer-filler interaction leading to changes in the properties of vulcanizates. The epoxidation reaction (in situ) was chosen to modify elastomers, such as polybutadiene (BR) and copolymer of styrene-butadiene-rubber (SBR)

5. Influência do método de preparação nas propriedades do óxido de ferro suportado. / Influence of preparation method on properties of iron oxide supported.
Styrene is one of the most important basic chemicals to produce valuable commodities such as polystyrene, acrylonitrile-butadiene-styrene and styrene-butadiene-styrene. It is commercially produced by the dehydrogenation of ethylbenzene in the presence of large amounts of steam at high temperatures of 600-700 oC. This process is thermodynamically limited and

6. Characterization and thermal behavior of polymer-modified asphalt
A styrene-butadiene-styrene modified asphalt cement was characterized by infrared, differential scanning calorimetry, thermogravimetric analysis and empirical tests such as ring and ball softening point, penetration and elastic recovery. After aging in the rolling thin-film oven, the polymer-modified asphalt presented structural changes relating to oxidation

7. Sintese, estrutura-morfologia e relação com propriedades macroscopicas do modificador de impacto poli (metacrilato de metila-co-butadieno-co estireno), MB&
Poly(vinyl Chloride), PVC, is an of thermoplastics more useful because exhibits many excellent properties, but impact resistence is not one of them. This properties can be improved with the mixture of impact modifiers in the PVC. In this work was studied the synthesis of poly(methyl methacrylate-co-butadiene-co-styrene), MBS, and the effect of his structure
