The thermal and photooxidative stabilities of high, linear low and metallocene grade polyethylenes are compared using FTIR and hydroperoxide concentration analysis and thermal methods (DSC, TGA). The thermal ageing of solid films follow the order LLDPE > metallocene > HDPE while for light stability the order is LLDPE > HDPE > Metallocene. Derivative UV and FTIR spectroscopic analysis of the three polyethylene types show that the vinyl types and concentrations are different and that they reflect… CONTINUE READING
