Evidence that metal carbonyls react with phosphinic acids to yield related polymers is presented. A more detailed presentation of the synthesis and properties of the polymers CrH2O OH OPR1R2O2x where R1 and R2 are phenyl andor methyl groups is given. Samples with molecular weights which appear to be considerably higher than the values observed for related systems were synthesized. These polymers display properties typical ofo lacipical of linear polymers, even though an octahedral metal is involved in the backboone and no chelate rings are present as blocking groups. Finally, they are representative of a rather large number of polymers currently being studied.
