Ermol'chuk L. Synthesis and investigation of properties of the functionalized liquid rubbers and their composites with secondary polymeric fillers.

The aim of dissertation is synthesis and investigation of properties of the functionalized hydrocarbon reactive oligomers and modified thermoplasts for further using in the creation of rubberplasts that contain rubber crumb and study of forming, structure and properties of these composite materials. The objects of investigation are syntesis of liquid rubbers with functional groups and the modification of raw materials. In the work the systematic study of the properties of the rubberplasts based on modified components (rubber crumb, secondary polyethylene and the modifier - reactive oligomer) has been started. The liquid rubbers with hydroxyl, epoxide, carboxylic, amine, and amide group have been synthezed. The relatioship of the influence of the chemical structure of functionalized liquid rubbers and modified thermoplasts on the peculiarities of forming and properties of rubberplasts has been found. It was allowed to work out new composite materials with improwed exploiting characteriztics.
