“…Sodium, 3, 42, 44, 46, 47, 66 ± 76 potassium, 75,77,78 and lithium 36, 74, 75, 77, 79 ± 81 alkoxides and also fluorinated alcohols (in the presence of triethylamine) have been used as nucleophilic agents. 3,48,82 Since some regularities of the formation of poly(fluoroalkoxyphosphazenes) have been considered in our previous review, 3 we do not discuss them here. We only would like to mention that the degree of chlorine substitution and the occurrence of the extremely undesirable side reactions of hydrolysis during the polymeranalogous substitution of chlorine in PDCP by sodium trifluoroethoxide, depend appreciably on the experimental conditions.…”
