Abstract

La invención se refiere al control en línea del peso molecular en procesos de polimerización de estado sólido continuos. En particular se dirige a un proceso de poliéster o a un proceso de poliamida, y más específicamente a un poli(etilentereftalato) (PET) o un poli(butilentereftalato) (PBT) o un proceso de polimerización de estado sólido (SSP) continuo de nylon 6,6. Un viscosímetro en línea funde y mide el peso molecular de la resina SSP y ajusta uno o más de las variables de proceso, es decir tiempo del reactor, pureza del gas inerte y temperatura del gas inerte para mantener un peso molecular de resina constante.
