The article presents the interdisciplinary research among organic synthesis, chemistry of polymers and ceramic technology. It presents the synthesis of monoacryloyl esters of fructose and glucose that is 1-O-acryloyl-D-fructose and 3-O-acryloyl-D-glucose, conditions of their polymerization and application in shaping of advanced ceramic powders by the so called gelcasting method. The paper presents the influence of carbohydrate esters on the viscosity of Al2O3 suspensions and microstructure of final ceramic samples. The results showed that synthesized esters of saccharides can play the role of organic monomers able to polymerize in situ and self-cross-linking compounds in gelcasting. The paper presents the proposed structure of polymeric network which is formed from acryloyl ester of glucose during gelcasting process. The paper describes rheological behaviour of slurries composed of synthesized substances and A2O3 powders, wetting angles of alumina substrate by synthesized compounds, differences in glass transition temperatures of polymers and the microstructure of obtained final ceramic samples.

The use of a novel chiral functional monomer system in molecular imprinting protocols is described. The monomer, dibenzyl (2R,3R)-O-monoacryloyl tartrate, possesses a hydroxyl moiety which can be used to direct template-functional monomer interactions during molecular imprinting polymerization. This system simultaneously positions benzyl ester-protected carboxyl groups in close proximity to the template, which upon deprotection yield recognition sites with stronger ligand-binding capacities.
