Influência da incorporação de poli(ácido lático) - PLA, de pó de madeira e outros aditivos no comportamento físico-mecânico do poli(hidroxibutirato) - PHB.
(Universidade Federal de São Carlos, 2004-04-30)
Polymeric materials are used today in the most varied sectors and the deleterious effects of their application, particularly in the short-term, have led to increasing environmental concern. On the other hand, innovative ...
Utilização da borracha natural no desenvolvimento de elastômeros termoplásticos
(Universidade Federal de São Carlos, 2010-05-28)
Dynamic vulcanization is a process of vulcanization of an elastomer during melt mixing with a thermoplastic. This process results in an elastomeric alloy material with the properties of a conventional thermoset rubber, but ...
Análise da influência das condições de processamento na morfologia e nas propriedades de blendas poliméricas PBT/ABS moldadas por injeção
(Universidade Federal de São Carlos, 2011-06-29)
A study on the correlation of blend morphology, properties, the injection molding process and manufacturing methods of polymeric blends constituted of PBT and ABS was proposed. Thus, uncompatibilized PBT/ABS blends have ...
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 ...
Estudo e desenvolvimento de blendas ternárias biodegradáveis a partir de poli(ácido lático), poli(álcool vinílico) e quitosana
(Universidade Federal de São Carlos, 2010-04-08)
The present study examined the use of poly(vinyl alcohol) as a compatibilizing agent between chitosan and PLA and as a diluent for chitosan in an approach where a dispersion chitosan in PVA produced by solution blending ...
