Розроблено метод одержання композиційних гідрогелевих трубчастих виробів підвищеної міцності на основі кополімерів 2-гідроксіетилметакрилату з полівінілпіролідоном. Метод полягає у формуванні гідрогелевих трубок з наступним осадженням з розчину у їх зовнішню поверхню зміцнювального шару на основі поліаміду, модифікованого полівінілпіролідоном. Одержані композиційні гідрогелеві трубки, які відзначаються достатньою міцністю, пружністю, еластичністю, а також здатністю витримувати внутрішній тиск в межах 24–43 кПа (180–320 мм рт. ст.).
