Abstract
A creep apparatus has been constructed for anin situ determination of length and length change. Using this apparatus, the creep behaviour of PVC thin films associated with quenching and ageing was studied. The more severe the quench through the glass transition temperature (T g), the greater is the instantaneous elastic deformation and the subsequent creep behaviour. As ageing proceeds, the quenched films gradually lose the ductility incurred by quenching. These results agree well with the well-known phenomena of physical ageing. Thus, the changes reflecting molecular mobilities due to quenching and ageing can be properly monitored by such a creep apparatus.
