The effect of crystallization temperature on the morphology of two Syndiotactic Polypropylene (sPP) was examined in terms of crystal dimensions and initial phase composition. Investigations show that the mechanical parameters correlated qualitatively with the phase composition, crystallite size and their orientation. It was found that the sPP fibers displayed the characteristic elastic behavior of the A25 polymer. The results show that the A 25 crystallites had higher modulus and strain hardening.

Abstract
The effect of crystallization temperature on the morphology of two Syndiotactic Polypropylene (sPP) was examined in terms of crystal dimensions and initial phase composition. Investigations show that the mechanical parameters correlated qualitatively with the phase composition, crystallite size and their orientation. It was found that the sPP fibers displayed the characteristic elastic behavior of the A25 polymer. The results show that the A 25 crystallites had higher modulus and strain hardening.File in questo prodotto:
