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 ...
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 ...
Análise da processabilidade de blendas PBT/ABS compatibilizadas in situ com copolímeros acrílicos
(Universidade Federal de São Carlos, 2007-12-14)
Poly(butylene terephthalate)/acrylonitrile-butadiene-styrene (PBT/ABS) blends show high toughness at room temperature, low ductile-brittle transition temperature and stable morphology when compatibilized. The flowability ...
Estudos microrreológicos da blenda PBT/SAN.
(Universidade Federal de São Carlos, 2006-09-22)
This work was motivated by the need of a better understanding of the
microrheological characteristics of polybutylene terephthalate, PBT, polymer
blends, such as the matrix phase PBT and the styrene-acrylonitrile, SAN
copolymer ...
