Abstract: 
У цій роботі наведено новий зелений метод кополімеризації 1,3,5-триоксану з ε капролактоном. У цій методиці використано Maghnite-H+ (Mag H+) як об’ємний зелений каталізатор. Різні методики були використані для підтвердження будови отриманого кополімеру. Також досліджено фактори, які впливають на реакцію кополімеризації. Одержані результати показали, що найкращий вихід кополімеру (46,3 %) отримано для полімеризації в блоці за температури 353 K протягом 8 годин.
