Presented PhD thesis are focused on polymer organic chemistry. It will be mainly focused on controlled polymerizations catalyzed by organo-metal or organic catalysts under inert atmosphere. Low molecular weight and macro-initiators as (multi)hydroxides and amines will be used. Biodegradable polyesters as products of these polymerizations are suitable for organic main-chains or on chain-ends post-functionalizations according to the monomer selection. The progress of the reactions and polymerization, effectivity of initiation as well as structure of products will be analyzed mainly by NMR, FTIR and MALDI spectroscopies. The example of polyesters synthesis is ring-opening polymerization of methylene-gamma-butyrolactones (monomers from renewable resources) and caprolactone and subsequent methylene double bond functionalization with the aim of epoxy group introduction or thiolene photo-reaction along the polyester backbone. Reaction with multicarboxylic acid (n>2, for example citric, malic, succinic acid) leads to formation of beta-hydroxyester networks with association-reversible topology capable to re-formation in the presence of catalyst.
