Kozak, N. V. published the artcileEffect of Cu bis(ethylacetoacetate) on rotational diffusion of paramagnetic probe TEMPO and thermooxidative degradation of polyurethane-PMMA semi-IPN, Application In Synthesis of 14284-06-1, the publication is Ukrainskii Khimicheskii Zhurnal (Russian Edition) (2005), 71(7-8), 122-127, database is CAplus.

Adding of copper bis(ethylacetoacetate) (CuAc) to PMMA-polyurethane semi-IPN was accompanied by the decrease in activation energy and rotational diffusion of the paramagnetic probe TEMPO. Thermooxidative degradation and structural changes of semi-IPN depend on the metal ion valency. Thermogravimetric anal. indicates slowing down of degradation of semi-IPN in the presence of CuAc at the initial stages. Increase of the amount of CuAc to 5% leads to the increased rate of degradation at >330°.

The reaction of triphenylboroxine with di-Et ethylidenemalonate in the presence of bis(ethoxycarbonylacetonato)copper(II) was investigated. When the reaction was carried out in pyridine, Cu powder precipitated and Cu(I) pentaborate-pyridine(1/6) crystallized From the filtrate, benzene (69.7%), biphenyl (13.9%) and 1-phenylethylmalonic acid (7.5%) were obtained. Several byproducts were also identified. Possible pathways for the formation of these products were suggested. The formation of biphenyl and 1-phenylethylmalonic acid was explained by a radical mechanism. By use of a large excess of di-Et ethylidenemalonate as solvent, 1-phenylethylmalonic acid was obtained in a 55.7% yield.

A new technol. of coupling reaction was studied, by which the simultaneous synthesis of poly (ethylene glycol succinate) oligomers and di-Me carbonate (DMC) was realized by the coupling reaction of ethylene carbonate (EC) and di-Me succinate (DMSu) over various metal Et acetoacetate complexes.

The photoinduced crosslinking of solid poly(vinyloxymethylmethacrylamide) containing transition metal chelate catalysts is accompanied by the formation of long-lived free radicals which can be detected directly up to 300 K. The only source of primary free radicals was the chelate mol. photodegradation The long-lived free radicals detected in the polymer matrix at room temperature may stimulate the creation of a new approach in the study of radical processes in solids.

Nizel’s’kii, Yu. M. published the artcileLinear and crosslinked polyurethanes containing nanostructuring coordination centers, Safety of Copper(II) ethylacetoacetate, the publication is Nanosistemi, Nanomateriali, Nanotekhnologii (2007), 5(2), 435-443, database is CAplus.

The in situ polymer-immobilized mono-, bi- and polyheteronuclear metal complexes are obtained in homogeneous polymers based on linear and cross-linked polyurethanes. Anal. of both EPR-spectra shape and copper-ion electron-spin parameters for isolated and immobilized mono- and polyheteronuclear metal compounds confirms a complexation between the modifier and electron-donating groups in linear and cross-linked polyurethanes. These complexes form the coordination linkages of macrochains in a polymer matrix. As revealed, the immobilization of monoionic copper ethylacetoacetate does not disturb tetragonal symmetry (D_2h or D_4h) of its chelate node. On the contrary, introduction of the polyheteronuclear metal complex into the polymer matrix is accompanied with essential distortion of the initial complex EPR spectra. Obtained systems are described as bottom-up metal-containing nanosystems, which include nanoscale structures of both organic nature (self-similar microheterogeneities typical for segmented polyurethanes) and metal-containing co-ordination junction points within the microphase or at the boundary.
