The crystalline structure, spherulitic crystallization and melting behaviour of isotactic
polypropylene (iPP) is comprehensively reviewed, illustrated and discussed. It is …

The paper is intended to summarize the studies devoted to the elucidation of the different
crystal structures and crystal morphologies and of the different conditions favouring one or …

The crystallization behavior after partial or complete melting of the α phase of iPP is
examined by combined differential scanning calorimetry (DSC) and optical microscopy …

The progress made in the understanding of the crystal polymorphism and morphology of
isotactic and syndiotactic poly (propylene)(iPP and sPP) is reviewed. In 1960, the crystal …

Many structural materials (metal alloys, polymers, minerals, etc.) are formed by quenching
liquids into crystalline solids. This highly nonequilibrium process often leads to …

Analyzing and understanding the structure and morphology of crystalline polymers has been
and remains to be a major challenge. Some of the issues have resisted analyses for …

The Polymeric Materials Encyclopedia presents state-of-the-art research and development
on the synthesis, properties, and applications of polymeric materials. This groundbreaking …

In-situ synchrotron small-angle X-ray scattering (SAXS) was used to follow orientation-
induced crystallization of isotactic polypropylene (i-PP) in the subcooled melt at 140° C after …

Intercalated nanocomposites of polypropylene (PP)/clay (PPCNs) were prepared by a melt
extrusion process using maleic anhydride modified PP (PP-MA) and organophilic clay. The …

CRYSTALLINE synthetic polymers generally exhibit highly anisotropic arrangements of the
polymer chains, which tend to lie parallel to each other. Indeed, chain-axis parallelism has …
