Investigation of the effects of different structure polymers on the properties of self-leveling mortars

The scope of the thesis aims to synthesize plasticizer polymers with different structures containing different functional groups (hydroxy, carboxylic, sulfonic ext.) that can be used in self-leveling mortars and to reveal the characterization of these polymers. In order to create an original study, it was aimed to make graft studies in the presence of a monomer that has not been revealed before. In addition, copolymers of monomers of different structures were synthesized with double/triple monomer combinations and their performances were determined. For this purpose, thesis studies were carried out in two main groups including the synthesis of starch-graft copolymers and macromonomers containing PEG chains and terpolymers of monomers with different functional groups. Starch-based graft copolymers were synthesized and characterized by the combination of monomers containing carboxylic acid and sulfonic acid. Similarly, terpolymers were synthesized and characterized by using 2-acrylamido-2-methyl-1-propane sulfonic acid and maleic anhydride monomers in combination with PEG containing macromonomers. All products were tested in a stable formulation of leveling floor screed to investigate their use in self-leveling mortars. The results obtained were compared with commercial plasticizers and the effectiveness, advantages and disadvantages of the successfully synthesized plasticizers were discussed. When all the results were evaluated, it was seen that the functional group amounts and distributions of the products changed depending on the monomer and initiator type, monomer/initiator concentration and reaction conditions, and their performances changed depending on their structural properties. In both groups of trials, products with commercial product performance were obtained.
