Abstract
A description is given of a “dual network” model which can be used as a basis for understanding correlations between the temperature dependence of shrinkage in biaxially oriented polypropylene films, along with film-forming parameters such as draw temperature and draw ratio. Although the model is presented in its most simplified form, and the structures of the networks are considered to be determined solely by their crystallinities, agreement between theory and experiment is promising.
