    Influence of the silicate modifier nature on the structure and properties of polycaproamide
    (Publishing House of Lviv Polytechnic National University, 2013) Levytskyj, Volodymyr; Kochubei, Victoria; Gancho, Andrij
    The influence of the nature and amount of the nanosized polyvinylpyrrolidone silicate modifier obtained as a result of the combined sol-gel transition on the supramolecular structure, as well as physical, mechanical and thermo-physical properties of polycaproamide has been determined. The modifier has proved to significantly increase the degree of crystallinity of polymer, and thus tensile strength at break, surface hardness and thermal resistance of a composite. Встановлено вплив природи і кількості нанорозмірного полівінілпіролідон-силікатного модифікатора, одержаного внаслідок сумісного золь-гель переходу, на характер надмолекулярных структур, фізико-механічні и тепло-фізичні властивості полікапроаміду. Показано, що модифікатор значно підвищує ступінь кристалічності полімеру і, як наслідок, міцність під час розривання, поверхневу твердість і теплостійкість композиту.
