1. Avaliação do efeito do agente compatibilizante (PP-g-MA) em misturas PP/Amido termoplástico
RESUMO O crescente desperdício de materiais plásticos no meio ambiente juntamente com a preocupação com a futura escassez do petróleo tem aumentado o interesse por polímeros biodegradáveis, como o amido. Nos últimos anos, o amido tem sido utilizado em misturas com diferentes polímeros sintéticos. Essas misturas têm sido compatibilizadas por meio d

2. Ácido cítrico como compatibilizante entre amido e poliéster em filmes tubulares produzidos por extrusão
Blends of thermoplastic starch and polyesters, as PBAT may be immiscible at the molecular level. The use of compatibilizing agents such as citric acid, could reduces the interfacial tension between polymer phases (starch/PBAT) improving the mechanical properties and water vapor permeability of films produced by extrusion. Extruders are used as chemical react

3. 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

4. Recuperação de Borracha EPDM Utilizando EPDM Modificado com Dodecanotiol como Agente Compatibilizante / Recuperation of the EPDM Vulcanized Waste Using EPDM Modified by Dodecanethiol as Compatibilizing Agent
In this work, the compatibilization technique was employed to recycle the ethylenepropylene- ethylidenenorbonene (EPDMR) vulcanized rubber. For this purpose, ethylenepropylene ethylidenenorbonene (EPDM) functionalized with dodecanethiol (EPDMDDSH) was prepared and used with compatibilizing agent. EPDM compositions containing EPDMR in different proportions we

5. 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
