Desenvolvimento e caracterização de blendas e de compostos empregando polímeros biodegradáveis
(Universidade Federal de São Carlos, 2004-10-25)
This work presents theoretical information and experimental data on the behavior of biodegradable polymers and blends of biodegradable PHB polymer with copolyesters that are also biodegradable. Binary mixtures were made ...
Caracterização físico-química de PET ramificado e de suas blendas com PET reciclado
(Universidade Federal de São Carlos, 2004-05-10)
The growing concern with the solid residues management, observed in the last decade, due to its huge amount and impact, has motivated the search for recycling processes, where these residues can be reprocessed to generate ...
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. ...
Grau de cisão de cadeia na degradação termomecânica de polímeros sob multiplas extrusões
(Universidade Federal de São Carlos, 2004-09-14)
One of the ways to follow the polymer degradation has been to calculate the average number of chain scissions (ns) that occurred during its
thermomechanical history. The average can be extended for each molecular weight ...
