Item The effect of poly (vinyl chloride) and filler on technological properties of polyester composites(Видавництво Львівської політехніки, 2017-12-23) Katruk, Diana; Levytskyi, Volodymyr; Lviv Polytechnic National UniversityThe paper determines the influence of polymer modifier (poly (vinyl chloride)) and finely dispersed inorganic filler on the elastic-deformation and thermophysical properties of polyester materials. The research discovers the change of deformation modulus, elasticity modulus, high elasticity modulus, surface hardness, Vica heat resistance, and technological shrinkage of modified polyester composites filled with calcium carbonate and aluminum oxide.Item Influence of the nature of metal-containing polymer-silicate filler on the physico-mechanical properties of polypropylene(Видавництво Львівської політехніки, 2017-12-23) Masyuk, Andrii; Paraschak, Oleksandr; Levytskyi, Volodymyr; Lviv Polytechnic National UniversityThe influence of Ni-containing polymer-silicate filler modified by polyvinyl alcohol on the physico-mechanical (surface hardness, strength at breaking, elastic modulus, coefficient of structure) properties of thermoplastic composites based on polypropylene has been found.Item Influence of poly(vinyl chloride) and polymer-silicate fillers on the properties of polyester resin(Lviv Polytechnic Publishing House, 2015) Katruk, Diana; Levytskyi, Volodymyr; Lviv Polytechnic National UniversityThe influence of polymer modifier poly(vinyl chloride) (PVC) and polymer-silicate fillers on the physicochemical regularities of structuring of unsaturated polyester resin have been investigated. It has been ascertained that addition of Zn-silicate fillers in polyester composition leads to slower curing speed, and the introduction of Ni-silicate fillers and PVC leads to accelerate the process of curing polyester oligomers. Physical-mechanical and corrosion properties of polyester materials modified by polyvinyl chloride and polymer-silicate fillers have been determined.Item Sorption properties of metal-containing polymer-silicate fillers(Lviv Polytechnic Publishing House, 2015) Masyuk, Andrii; Levytskyi, Volodymyr; Lviv Polytechnic National UniversitySorption properties of metal-containing polymersilicate fillers on regarding to different acid-base indicators have been investigated. The effect of the nature of metal and polymer modifier on the amount of active centers and specific active surface area of such material was determined. Moisture absorption of modified and not modified silicate materials has been found.
