Generalized kinetic master plots for the thermal degradation of polymers following a random scission mechanism
(American Chemical Society, 2010)
In this paper, the f(α) conversion functions for random scission mechanisms have been proposed to allow for the construction of generalized master plots suitable for these kinds of mechanisms. The master plots have been ...
