The thermal antioxidant action of Sanduvor NPU in polypropylene film has been examined at the 0.1% w/w concentration level. Infra-red and second-order derivative u.v.-visible spectroscopic techniques were used to monitor degree of oxidation in the films and stabiliser photodecomposition behaviour re
