Poly(lactic acid) (PLA) is one of the most important ecological thermoplastics due to its good mechanical properties. In light of this, investigations related to the effects of PLA processing parameters are important as they affect the final product performance. This work aimed to determine the viscosity-temperature coefficient (β) and pseudoplastic index (n) of PLA and estimate its degradation rate during processing using an internal mixer. The viscosity coefficient was determined applying different processing temperatures at the same rotors rotation rate, which allowed estimating β = 0.048 ◦C−1. PLA’s pseudoplastic index (n) under the tested conditions suggested a value of approximately 0.71. PLA’s degradation rate was around 4% under rotor rate of 120 rpm and temperature of 190 ◦C.

El poli(ácido láctico) (PLA) es uno de los termoplásticos ecológicos más importantes en la actualidad, debido a sus buenas propiedades mecánicas. En vista de esto, las investigaciones sobre los efectos de los parámetros de procesamiento de PLA son importantes, ya que afectan el rendimiento final del producto. Este trabajo tuvo como objetivo determinar el coeficiente de sensibilidad de la viscosidad con la temperatura (β) y el índice de plasticidad (n) del PLA, así como estimar su tasa de degradación durante el procesamiento en un mezclador interno. Para el coeficiente de viscosidad del PLA se adoptaron diferentes temperaturas de procesamiento y la misma velocidad de rotación de los rotores, lo que permitió estimar β = 0,048 °C-1. El índice de plasticidad (n) del PLA en las condiciones ensayadas sugirió un valor de aproximadamente 0,71. Se encontró que la tasa de degradación que sufrió el PLA fue de alrededor del 4%, utilizando una rotación del rotor de 120 rpm y una temperatura de 190 °C.
