Abstract

Способ получения перекисных перфторполиэфиров путем окисления тетрафторэтилена кислородом в жидкой фазе, включающей растворитель и в присутствии химического инициатора, при давлении между 2 и 15 абсолютных атм и использовании мольного соотношения тетрафторэтилена и химического инициатора выше 35. Способ позволяет увеличивать молекулярный вес перфторполиэфиров при том же самом содержании перекисного кислорода.
