Nascent melt polymerized condensation polymers: morphology and electron diffraction crystal structure characterization

摘要

We have developed a general technique, termed confined thin film melt polymerization (CTFMP), for simulaneous polymerization-crystallization of condensating polymers as single crystals (SCs) and/or single disclination domains (SDDs) (if liquid crystalline (LC) that are dieal for electron diffraction (ED). They consist of ca 100 A thick lamellae yielding [001]ED patterns. Thus of concern are ways of obtaining ED patterns with 00e reflections. As examples we consider poly(2,6-oxynaphthoic acid) (PONA) and poly (ethylene naphthalate) (PEN).
