Lamellae in Melt-Crystallized Polymersen preparation prior to electron microscopy, principally permanganic etching..Spherulites are constructed from a framework of individual dominant lamellae which diverge when they branch, often at giant screw dislocations distributed in space. In banded spherulites the dislocations are isochiral..The

Structure and Growth of Polymer Single Crystals as Illuminated by Morphological Observationsre sensitive. The isohypse decoration method and in situ melting experiments show that the stem length largely exceeds its thermodynamic lower bound. The profile of melt grown crystals of PE is predicted from a single Klein-Gordon equation which encompasses nucleation theory, generalization of this

Melting of Polymer Crystalsompact, disentangled molecules in solution grown single crystals expand rapidly to form random coils on melting; no molecular weight dependence of the time for the molecular coils to expand is found. On melting, isolated extended molecules randomise much more slowly and show a strong molecular weigh

Morphology, Chain Folding and C-LC Transitions in Liquid Crystal Polymer Single Crystalsfor several random terpolymer polyester LCPs having a nearly equimolar amount of a flexible segment dicarboxylate (4–7 CH.), oxybenzoate and dioxyphenyl. In all cases, in thin films and on free surfaces, folded chain lamellae are observed. High temperature electron diffraction has permitted characte

Crystallization and Gelation in the System iPS/CIS-Decalin and Intermediate Phaseseutron scattering. The thermal behaviour has been investigated as a function of the annealing temperature and the temperatureconcentration phase diagram has been established. The existence of two phases between the ., obtained at high undercooling, and the ., obtained at low undercooling, is demonst

Only a few books have beenfully devoted to the crystallization of polymers in the past. .This book contains the proceedings of the NATO ARW devoted to the`Crystallization of Polymers‘ which took place in Septem
