✦ Synopsis
Novel Pt-containing polymers derived from Zeise salt and polystyrene-polybutadiene diblock (PS-PB) and triblock (SBS) copolymers have been synthesized. The comparison of complex formation peculiarities of Pd-, Rh-, and Pt-containing polymers derived from SBS with 72 wt.-% of PB and PS-PB with 15 wt.-% of PB displayed that a short PB block in PS-PB allows to maintain solubility of organometallic polymers even if intermolecular complexation is probable. Such a solubility was found to be provided by micellization in Pd-, Pt-, and Rh-containing polymers derived from PS-PB. Moreover, crosslinks formed due to complexation were shown to contribute to micellization: iron carbonyl complexes immobilized on PS-PB, where solely intramolecular complexes can be formed, do not provide micellization.
