Recently, there is an increased interest in preparation of polymers using compounds originated from renewable resources. Known dilactide available from sugar cane, corn or potatoes as well as various 5-membered butyrolactones found in plants seems to be promising monomers for biocompatible and biodegradable polyesters synthesis. Tulipalin A (α-methylene-γ-butyrolactone, MBL) found in tulips is one of the promising monomer, thanks to two different functional groups, i.e. lactone ring and highly reactive exocyclic double bond, in its structure. Research efforts of the thesis will be focused on ring-opening copolymerization of lactone monomers to enhance versatility of the resulting polyesters. Homo- and random co-polyesters will be prepared by ring-opening copolymerization of lactones as ε-caprolactone or L-lactide with renewable γ-butyrolactone monomers, containing double bond suitable for various functionalizations. The unsaturated groups in the monomer or along the polyester chains will enable (post)modification by thiolene chemistry under mild conditions of photo-initiation. Post-functionalization contributes to the possibilities of synthesis of polymeric materials with tailored degradability, hydrophobicity, functionality or other properties
