The frontal polymerization of metal-containing monomers on
the base of acrylamide (AAm) complexes of transition and noble metal
nitrates M(AAm)[x](H[2]O)[y](NO[3])[2] (M = Co, Ni, Fe, Cu, Zn, Cd,
Ba, Pd, Rh) and properties of the products obtained are studied. This
is a first example of thermal (353-433 K) initiation of frontal
polymerization without any chemical initiators. By examining the
kinetics of thermolysis and evolution of gaseous products of
transformation we have concluded that nitrogen oxides (NO[2], NO,
N[2]O) formed at partial oxidation of nitrate groups are able to
initiate the reaction. Occurring of reaction front and a
self-sustained thermal wave are determined by structural-chemical and
energy factors. The ratio of thermal characteristics affect
self-organization of such systems: a self-sustained frontal mode of
polymerization and its stationary velocity. We succeeded first in
carrying out frontal copolymerization of acrylamide complexes with
traditional monomers. The main copolymerization parameters are
estimated. The ratio of thermal characteristics affect
self-organization of such systems: a self-sustained frontal mode of
polymerization and its stationary velocity. Following controllable
thermolysis of metallopolymers formed or controlled change of frontal
polymerization into burning regime leads to the formation of
metallopolymer nanocomposites. The yield product is metal (or metal
oxides) nanoparticles stabilized by pyrolized polymer matrix. The size
of the particles is about 6 to 30 nm, polymer shell has the same
sizes. The novel approach for synthesis of palladium immobilized
catalysts via frontal polymerization of acrylamide complexes into
surface of inorganic oxides is elaborated.
