Modificação do Poli(hidroxibutirato) PHB com nucleantes e com o copolímero (etileno-co-acetato de vinila) - EVA
(Universidade Federal de São Carlos, 2008-03-19)
In this work, we sought to modify PHB, processing it in the melted state, and to
evaluate the effect of the modifications on its mechanical properties and
biodegradation characteristics. The following systems were therefore ...
Monitoramento em tempo real da morfologia na extrusão da blenda polimérica polipropileno/ nylon 6.
(Universidade Federal de São Carlos, 2006-09-01)
The aim of this work is to assess in real time the morphological
parameters of polypropylene and polyamide 6 blends during the extrusion
process. An optical detector based on the visible light transmitted and extinction
principle ...
Desenvolvimento de um detector de espalhamento de luz LASER de baixo ângulo LALLS operando em tempo real na extrusão
(Universidade Federal de São Carlos, 2005-12-08)
In the present work a prototype of a low angle laser light scattering was developed and installed in an extruder in order to operate in real time. The equipment was built by the research group of which the author is member, ...
Influência dos parâmetros de Processamento e da composição na morfologia de resinas ABS.
(Universidade Federal de São Carlos, 2004-08-24)
The present work is about the influence of processing parameter and composition on the morphology of acrylonitrile-butadiene-styrene (ABS)resins. The ABS grades chosen are commercial products with high rubber content, i. ...
Dispersão seletiva de argila montmorilonita em blendas poliméricas de PA6/ABS
(Universidade Federal de São Carlos, 2009-08-25)
For some applications toughening of polyamide is important. This can be accomplished through the addition of an elastomeric phase to the polyamide matrix with the drawback of a reduction in the stiffness and strength of ...
