Fractionated syndiotactic polypropylene (sPP) samples with homogeneous tacticity were annealed at diΓΎ erent temperatures. The inΓ½uence of syndiotacticity and annealing temperature on the double melting peak phenomena were investigated. It is found that all fractions show double melting peaks at 75ΓC
The lamellar morphological information and subsequent melting behaviour of syndiotactic polypropylene (s-PP) samples isothermally crystallized at crystallization temperatures ranging from 30 to 95 Β°C have been investigated using a combination of wide-angle X-ray diffraction (WAXD), smallangle X-ray
