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 ...
Desenvolvimento de blendas poliméricas PVC/NBR através de processamento reativo e vulcanização dinâmica in situ
(Universidade Federal de São Carlos, 2008-02-28)
Dynamic vulcanization is a process of vulcanization of an elastomer during melt mixing with a thermoplastic which results in a material with better chemical and mechanical properties at high temperature. The PVC/NBR blends ...
