Summary: The possibility of applying basic aluminum carboxylates as the cross-
linking monomers in radical polymerization processes as well as the initiators for
ATRP of styrene and coordination ROP of heterocyclic monomers was examined. It
was established, that aluminum carboxylates containing in their structure the acrylic
and lauric acids derivatives show high activity in the copolymerization with vinyl
monomers which results in the hybrid works formation. In the typical
ATRP conditions, polymers grafted with styrene are obtained while basic aluminum 2-
bromopropionate is used as the initiator. posites . core-shell nano-
spheres can be obtained in this way at low degree of polymerization. Nanoparticles of
basic aluminum caroboxylates when reacted with triethylaluminum show high
activity as initiators in the polymerization processes of e-caprolactone, trimethylene
carbonate as well as propylene and ethylene oxides. Cross-linked products in the form
of a gel were formed as the result of ROP in such systems. However, linear polymers
