Crystal Structure, Morphology and Configuration of Nascent Condensation Polymers

9616255过去几年的GEIL研究表明，受限薄膜熔融聚合技术对于凝聚聚合物、液晶(LCP)和柔性聚合物的片状单晶的生长具有普遍的适用性，这些聚合物几乎是晶体结构的电子衍射(ED)研究的理想对象。它们通常在性质上约为100个粗大的延伸链，分子轴垂直于片层。这项赠款下的研究的目标是利用ED和一些补充技术，在许多重要的领域，包括液晶聚合物、晶体到中间相的转变和晶体结构测定，开发CTFMP和相关的样品制备技术。这项研究将有助于提供重要聚合物材料的结构和相变的基本知识。***

9616255 Geil Research over the last several years suggests that the confined thin film melt polymerization (CTFMP) technique is of general applicability for the growth of lamellar single crystals of condensation polymers, liquid crystalline (LCPs) and flexible polymers that are near ideal for electron diffraction (ED) studies of crystal structure.They are generally on the order of 100 thick, extended chain in nature, with the molecular axes normal to the lamellae. The research under this grant has the goal of exploiting CTFMP and related sample preparation techniques, utilizing ED and a number of supplemental techniqes, in a number of areas of significant interest including liquid-crystalline polymers, crystal-to-mesophase transitions, and crystal structure detepminations. %%%% This research will help to provide the underlying knowledge of the structure and phase transitions of important polymeric materials. ***
