Does anyone know where I might go about looking for numerical data about the comparative rates of chain scission and crosslinking in irradiated (preferably by electron-beam) PLA? So far all of the research I have looked at includes either a description of both happening or vague references to one happening more than the other.
Dear Robert Blanchard, there is no specific ratio, it depends on experimental conditions. Sometimes both are decreasing. The following documents deals with irradiation of PLA. My Regards
