Abstract : A new class of coordination polymers, poly(bis(phosphinato)-fluoroalanes), (A1(F)(OPRR'O)2)n, where R,R' = alkyl, phenyl or benzyl, was prepared and studied. The properties of these polymers are influenced by the phosphinate (R) substituents; polymers having n-alkyl groups with more than five carbons are flexible and exhibit unusual hydrolytic stability. A polymer was obtained with a degree of polymerization of 104 by incorporating a 2:1 ratio of benzyl(n-heptyl) and di-n-octyl phosphinate groups. The properties of the flexible materials are consistent with linear rather than highly crosslinked or network systems. Feasible structures are proposed for the polymers. (Author)
