Abstract

In this study, the effect on the physico-chemical behavior of linear low density polyethylene (LLDPE) films of the addition  of  a  pro-oxidant  additive  was  evaluated.  The  concentrations of  the  additive  employed  were 0.5%, 1% and 2%. The  films were subjected to  accelerated aging in  an  oven.  The  properties were  studied by tensile tests, differential scanning calorimetry (DSC),  thermogravimetry (TGA) and  Fourier transformed infrared spectroscopy (FTIR). It was found that after the induction period the carbonyl band was detected. The carbonyl index increased with the percentage of additive and with degradation time. The characteristic bands of the hydroxyl group and unsaturations were also detected. The thermal stability of the films decreased with the percentage of additive as a function of time.
