Abstract

Abstract 1. POLYPHOSPHAZENES THE SKELETAL CHAINS OF WHICH COMPRISE RANDOMLY REPEATING UNITS REPRESENTED BY THE GENERAL FORMULAS -(P(-O-R)2=N)- AND -(P(-O-R)(-O-W)=N)- WHEREIN EACH R IS A MONOVALENT RADICAL SELECTED FROM THE GROUP CONSISTING OF ALKYL, FLUOROALKYL, ARYL, SUBSTITUTED ARYL AND ARYLALKYL AND NOT EVERY R IN THE POLYPHOSPHAZENE IS REQUIRED TO BE IDENTICAL TO EVERY OTHER R; AND EACH W IS A MONOVALENT GROUP CONTAINING -NH OR -NH2 FUNCTIONALITY, AND WHEREIN W IS SELECTED FROM THE GROUP WHICH CONSISTS OF -R''-NH-R", -R"''-NH2 AND -CH2-CH2-X<(-CH2-CH2-NH-CH2-CH2-) WHEREIN R'' IS (-CH2-)A OR -C6H4$CH$A WHEREIN A IS AN INTERGER FROM 1 TO 4, AND WHEREIN X REPRESENTS CH OR N,R" REPRESENTS LOWER ALKYL WITH UP TO 4 CARBON ATOMS; R''" REPRESENTS ALKYL, ARYL, ARALKYL, ALKYLARLY, AND THE ARYL GROUP IS CARBOCYCLIC OR HETEROCYCLIC; AND THE RATIO OF R/W IS FROM ABOUT 99.5/0.5 TO 65/35.
