Description

The objective of this work is to study the effects of gamma radiation induced in molecular structure of Poly(methyl methacrylate), ACRIGEL. Viscosity analysis, spectroscopy (FT-IR) and differential scanning calorimetry (DSC) were carried out in irradiated PMMA. The value of G = 1,5 (scission/100 eV) it was found through viscosity-average molecular weight. (author). 6 refs., 4 figs
