Abstract

Isothermal annealing technique was used to accelerate the ageing process on prefabricated highly crystalline polypropylene thin films to investigate the specification failure of such films. Samples were held at a constant temperature of 125 °C, for different periods of titne ranging from 1 to 10 hours. A mechanism to describe the observed variations has been proposed. A model for the macrostructure is introduced which explains the observed data. The suggested model helps to identify the role o f relaxation processes by ageing. The periodic changes of the polymer structure were proven by infra-red technique.
Infra-red dispersion properties of the samples were measured in the vvavelength range 2-6.5 micron. The technique exhibited a structural periodic time of 4 hours.
