“…[48] It was found that the polymers with cationic cyclopentadienyliron moieties pendent to their backbones (37) possessed higher glass transition temperatures, but lower thermal stability than their ferrocene-based polymeric analogs (38).

This article provides a comprehensive review of the synthesis, properties and applications of organometallic polymers of the transition metals. The different classes of organometallic polymers are described according to their structural make‐up, as well as by their methods of synthesis. A number of examples of each class are given to emphasize the richness and diversity in these areas of research. In addition to linear polymers, hyperbranched, crosslinked, star and dendritic polymers are also described. The properties that transition metal‐containing organometallic polymers possess, as well as the applications that these materials have found in various domains are highlighted. magnified image

Synthesis and characterization of ferrocene-containing main-chain polyamides are reported in this article. A new, interesting type of organometallic monomer (FDADO) based on ferrocene was prepared by interfacial condensation of 1,1 -dichlorocarbonyl ferrocene with 2 mol 1,8-diamino-3,6-dioxaoctane (DADO). A series of ferrocene-based polyamides was prepared via polycondensation of the ferrocenyl diamine (FDADO) with different diacid chlorides using two different methods. The monomer and polymers were characterized by elemental analysis, infrared and NMR spectroscopy. The thermal stability and behavior of the synthesized polymers were evaluated by thermal gravimetric analysis (TGA), dynamic mechanical thermal analysis (DMTA), and differential scanning calorimetry (DSC). The crystallinity of polymers was examined by X-ray diffraction analysis. Inherent viscosity, solubility and flame-retardancy of the polymers were also studied. The obtained polymers showed good heat-resistance and flame-retardancy, and improved solubility vs generally reported polyamides in some common organic solvents.

BACKGROUND: Although a role for resection of solitary metastases from renal cell carcinoma (RCC) has been described, the utility of surgery in patients with multiple sites of disease has been less well defined. The authors report the survival of patients who underwent complete metastasectomy for multiple RCC metastases. METHODS: The authors identified 887 patients who underwent nephrectomy for RCC between 1976 and 2006 who developed multiple metastatic lesions. The impact of complete metastasectomy on survival was evaluated controlling for the timing, location, and number of metastases and for patient performance status. RESULTS: Of 887 patients, 125 (14%) underwent complete surgical resection of all metastases. Complete metastasectomy was associated with a significant prolongation of median cancer-specific survival (CSS) (4.8 years vs 1.3 years; P < .001). Patients who had lung-only metastases had a 5-year CSS rate of 73.6% with complete resection versus 19% without complete resection (P < .001). A survival advantage from complete metastasectomy also was observed among patients with multiple, nonlung-only metastases, who had a 5-year CSS rate of 32.5% with complete resection versus 12.4% without complete resection (P < .001). Complete resection remained predictive of improved CSS for patients who had 3 metastatic lesions (P < .001) and for patients who had synchronous (P < .001) and asynchronous (P ¼ .002) multiple metastases. Moreover, on multivariate analysis, the absence of complete metastasectomy was associated significantly with an increased risk of death from RCC (hazard ratio, 2.91; 95% confidence interval, 2.17-3.90; P < .001). CONCLUSIONS: The current results indicated that complete resection of multiple RCC metastases may be associated with longterm survival and should be considered when technically feasible in appropriate surgical candidates.
