Abstract

Спосіб одержання сополимеру тетрафторетилену водно-емульсійної сополимеризацією тетрафторетилену як комономер використовує гексафторпропілен чи перфторпропіленперфторвініловий естер. Винахід стосується способу полімеризації та кополимеризації фторованих мономерів у водній дисперсії в присутності радикалів-зародків (ініціаторів) Запропонований спосіб відрізняється швидкістю полімеризації, яка значно вище, ніж швидкість, що може бути досягнута традиційними способами за аналогічних робочих умов.
