Young’s modulus of highly oriented polypropylene films

Young’s modulus of highly oriented polypropylene films

Anomalously high values of Young's modulus were established in polypropylene films with λ = 33.7 and the range of a nonlinear increase in the region of λ = 5-7 was found, caused by recrystallization processes. To explain these results, we proposed considering Young's modulus in polypropyle...

Zusammenfassung:Anomalously high values of Young's modulus were established in polypropylene films with λ = 33.7 and the range of a nonlinear increase in the region of λ = 5-7 was found, caused by recrystallization processes. To explain these results, we proposed considering Young's modulus in polypropylene as a linear combination of constituents which are only a function of the temperature and degree of drawing separately.[PUBLICATION ABSTRACT]
