Abstract

The film-forming material, Metolose, was studied by positron annihilation spectroscopy. It is known that above a given concentration the plasticizer (PEG) forms a separate phase. The controlled ageing of the films showed that there is a difference between the ageing processes of the monophase and that of the separated phase films. The ageing consists of a fast and a slow step in both cases. Our PAS measurements showed that this slow process is hindered in the phase-separated samples.
