Influence of morphological factors on tensile properties in the pre-yield region of isotactic polypropylenes

ABSTRACT We examined the molecular and structural variables that govern tensile properties of isotactic polypropylene forming spherulitic morphology. The polypropylenes were crystallized in

such a manner as to develop as a wide range as possible in the values of the independent structural variables that describe the solid state. The initial deformations depend strongly on the

amorphous regions but are independent of the spherulite size and lamellar thickness. At yield point the lamellae within spherulites were found to be fragmented and replaced by a highly

oriented fibrous structure in the post-yield region. SIMILAR CONTENT BEING VIEWED BY OTHERS IMPACT OF STATISTICAL POLY(PROPYLENE CO-ETHYLENE) ON THE THERMO-MECHANICAL PROPERTIES OF
