“…The product was recovered after evaporation of the solvent under vacuum. Then, it was pyrolyzed at 600°C in the self-generated atmosphere [20] for 95 min under static and non-isothermal conditions to reduce the metals (iron and platinum) inside the TiO 2 matrix and convert them into the desired L1 0 fct phase. The kinetics of gas release during pyrolysis was monitored using a membrane zero manometer.…”

“…[20] The magnetic hysteresis behavior of as-synthesized FePt nanoparticles is analyzed in detail. The two main features of the proposed synthetic route are i) introduction of metal ions at the gel-formation stage (which allows for the synthesis of bi-and polymetallic nanocomposites), and ii) reduction of metals inside the matrix during the pyrolysis stage (intermatrix synthesis) without the use of any additional reducing agents; hence, the acetylacetonate (AcAc) organic ligands most probably act as reducing agents.…”

“…13 The structure and magnetic properties of Fe (II) and Co (II) acrylate complexes were investigated by Lawecker et al 14 The kinetic peculiarities of the thermal transformation of unsaturated metal carboxylates and properties of metal polymer nano composites formed have been studied. 15 By thorough literature survey we could not find any report based on the functionalization of linear low density polyethylene (LLDPE) with metal acrylates and metal methacrylates. In the present investigation, we took this job as a challenge and successfully synthesized the calcium diacrylate (CDA) and CDM divinyl monomers and functionalized the LLDPE backbone with CDA and CDM.…”

Calcium diacrylate (CDA) and calcium dimethacrylate (CDM) divinyl monomers were synthesized by a solvo thermal method. The FTIR spectra showed a peak at 1650 cm À1 due to the presence of a C¼ ¼C for both CDA and CDM. Proton NMR and carbon NMR confirmed the structure of CDA and CDM synthesized by a solvo thermal method. DSC determined the melting temperatures of CDA and CDM. XRD indicated the presence of a d 110 plane peak for CDA and CDM. The % weight residue that remained above 700 C in TGA method confirmed the higher thermal stability of CDA.Thus, synthesized CDA and CDM were surface grafted on linear low density poly(ethylene) (LLDPE) at 160 C under inert atmosphere by thermolysis method. FTIR confirmed the presence of C¼ ¼O stretching due to CDA and CDM in LLDPE backbone after thermolysis reaction.1 H-NMR confirmed the chemical grafting of CDM onto LLDPE.

“…Such an approach is conceptually unique, and the systems under consideration are chemically self-regulating ones and thus they have embodied the best solution of the given problem (i.e., the nanoparticles formation and stabilization in polymer systems). Although at present the method is realized on transition metal acrylates and maleinates only [36], there are no principal limitations for its use with the other types of metallomonomers.…”

The processes of thermal decomposition play an important role in various practical fields including metallurgy, mineral conversion processes, pyrogenic chemical technology, pyrolysis and thermal treatment of wood and coal, combustion of natural and synthetical fuels, coal carbonization, the prevention of grain spontaneous ignition, and so on. There is still a need for scientifically well-founded approaches to control the thermal decomposition of materials. Many studies focus attention on the chemical transformations and reactions in the pyrolized systems and on the creation of mathematical models of such processes as the major parts of the theory of chemical decomposition of complex substances.Thermolysis is widely used in the synthesis of nano-sized metallopolymer composites. This is a result of the specifics of the preparation of such materials. In spite of a variety of the methods for the preparation of metallopolymer nanocomposites, there are two principal routes: "bottom-up" and "top-down."
