The Synthesis and Structure of Polyphosphazenes.
Abstract
Film-forming polyphosphazanes have been delayed based in mixed substituent polymers, especially those with both hydrophilic and hydrophobic substituents. The surface hydrophobicity of such polymers has been studies as a function of the side group ratios. A variety of different synthetic methods have been devised and developed for the linkage of metal-containing groups to a phosphazane skeleton. These metallophosphazenes constitute a new class of compounds which, at the high polymeric level, should give rise to unusual electronic, catalytic, or thermal behavior. Major progress has been made in understanding the relationship between molecular structure and physical properties of polyphosphazenes by the synthesis and X-ray diffraction study of a series of linear short chain analogues of the high polymers to explore the reasons for unusual phenomena such as the low glass transition temperatures and the crystallization behavior.
