Synthesize And Properties Study On The Phosphorus Containing Poly(aryl Ether)s

Poly (aryl ether)s (PAE)s are used as thermoplastic materials with highthermal durability, environmental durability, excellent chemical stability andhigh thermal intensity. Phosphorus containing PAES are even endowed someexcellent performance with the radical of phosphorus. Investigation onphosphorus containing flame resistant materials is always the important work ofpeople. In he near future phosphorus containing polymers are become the focusof space appliance materials because of their atomic oxygen resistance andspace optical characters.The objective of the thesis is to synthesis the polymer materials withphosphorus containing in there backbones and investigate the influence of theflame resistance and space appliance characters when phosphorus radical beingadded.To get the designing polymers we start the molecular designing first. Thenovel phosphorus containing polymers were synthesized by the aromaticnucleophilic displacement reaction of synthesized phosphorus containingdifluorides monomer and two kinds of similar structure bisphenolsAfter detailed characterization of the polymers through MS, elementaryanalyze, DSC, FTIR and H-NMR, we proved that we get the prediction 1materials.We study on the basis characters of the two polymers by the analyze means:1. high molecular andηthey have;2. soluble little in the polar organic solvent in common use at room temperature they are;...
