Monitoramento em tempo real da orientação molecular de poliestireno e em misturas com polimetilmetacrilato durante a extrusão
(Universidade Federal de São Carlos, 2011-03-02)
In this work it was studied the flow orientation of pure polystyrene and its diluted mixtures with polymethylmethacrylate as second phase during extrusion process by in-line monitoring of the polarized transmitted light ...
Desenvolvimento de uma matriz de fenda instrumentada para o monitoramento reo-óptico do processo de extrusão
(Universidade Federal de São Carlos, 2015-03-13)
A novel slit-die flow cell is presented for the evaluation of extrusion thermo-mechanical history on the flow character of polymers. The rheo-optical concept is claimed once both flow-birefringence and rheological character ...
