Cristalinidad y temperatura de fusión de polietileno en la zona de doble fluencia
Resumen
El fenómeno de doble fluencia fue estudiado, después de retirar la deformación uniaxial, en especímenes de polietileno deformados a una rapidez constante y a distintas elongaciones. El grado de cristalinidad y la temperatura de fusión fueron determinados como función de la elongación a la cual fueron sometidos. Los resultados señalan que se produce una fusión parcial seguida de una recristalización.
