Abstract:

This article concerns the catalysis of polycondensations and polyadditions its scope is limited to the use of metal derivatives and enzymes. Palladium, nickel, ruthenium and copper derivatives are studied as catalysts of carbon-carbon forming polycondensations when applied to polymeric systems and models side reactions are analyzed. Palladium-derivatives mainly concern Heck and Suzuki polycondensations. The influence of the nature of the catalyst on reactivity is also an important part of this article it is not limited to carbon-carbon forming reactions but also to other polycondensations such as polyesterifications. Some examples concern systems activited by Ni(0), CsF and rhodium complexes as activators. A general bibliography of enzyme-catalyzed polycondensations is given however only polyesterifications are studied, particularly aliphatic, unsaturated and aromatic polyesters side reactions and linear chains / cycles equilibriums are particularly studied.
