Abstract

Se refiere a un proceso en el cual los iniciadores que tienen una vida media de desde 0,001 hora hasta 0,05 hora a la temperatura de polimerización se dosifican a una mezcla de polimerización. La dosificación de dicho iniciador permite el control mejorado de la velocidad de polimerización y velocidades más rápidas de polimerización, y el proceso generará un polímero con niveles muy bajos de iniciador residual.
