1. Efecto de la adición de bentonita sobre las propiedades ópticas de diferentes materiales compuestos poliméricos
ABSTRACT In this work, composite materials were obtained by the incorporation of bentonite to biodegradable and synthetic polymeric matrices. Commercial (BE) and natural (BM) bentonite samples were employed, as well as three different polymeric matrices: thermoplastic corn starch (TPS), high density polyethylene (HDPE) and a poly(styrene-b-butadiene-b-styren

2. Effect of reinforcement nanoparticles addition on mechanical properties of SBS/curauá fiber composites
Composites of styrene-butadiene-styrene triblock copolymer (SBS) matrix with curauá fiber and/or a nanoparticulate mineral (montmorillonite clay - MMT) used as reinforcing agents were prepared by melt-mixing. The influence of clay addition on properties like tensile and tear strength, rebound resilience, flex fatigue life, abrasion loss, hardness and water

3. Influence of compatibilizer on blends degradation during processing
The thermomechanical degradation of blends made from polypropylene and polystyrene, with or without compatibilizer, was studied using an internal mixer coupled to a torque rheometer. The blends processed without compatibilizer presented regular and expected results regarding torque reduction, with evidence of chain scission. The blends processed with the blo

4. Efeitos de aditivo tipo óleo e enxofre na reologia de asfaltos modificados com SBS
O uso de asfaltos modificados com polímeros tem crescido significativamente nas últimas décadas em função do aumento da densidade de tráfego, da carga por eixo nos veículos e da pressão dos pneus. Estes ligantes proporcionam o aumento a vida útil e a redução do custo de manutenção das rodovias. Os polímeros mais utilizados na modificação de a

5. Estudo da tenacificação do poliestireno com elastômeros butadiênicos / Polystyrene toughening by butadiene elastomers
This Dissertation describes a study about the toughening of polystyrene with different types of polybutadiene (high-cis, low-cis and styrene - butadiene diblock or triblock copolymers). These materials (High Impact of PolyStyrene HIPS) were performed by melt blending. The mechanical properties (hardness, tensile strength and impact strength); morphology and

6. Properties of SBS and sisal fiber composites: ecological material for shoe manufacturing
The worldwide trend toward using cheap, atoxic and durable materials from renewable resources contributes to sustainable development. Thus, the investigation of the potential use of vegetal fibers as reinforcing agent in polymeric composites has gained new significance. Sisal fiber has emerged as a reinforcing material for polymers used in automobile, footwe

7. Rheological evaluation of polymer-modified asphalt binders
Currently, the most used polymer for asphalt binder modification is the thermoplastic elastomer styrene butadiene styrene (SBS) and aromatic oil is commonly added to the mixtures to improve their compatibly. This paper proposes the use of oil shale from sedimentary rock as a compatibilizer agent for polymer-modified asphalt binder (PMB). PMBs were produced b

8. Funcionalização do copolímero em bloco estireno-butadieno-estireno (SBS) e sua utilização em misturas com nylon 6
In this work chemical modification of styrene-butadiene-styrene copolymer with glycidyl methacrylate was carried out in an internal mixer through radical reactions. Dicumyl peroxide was used as initiator. Grafting reactions with maleic anhydride were also performed. During reactions torque was monitored continuously. Reactions products were characterized by
