Claims (1)
- Фторированные термопластиные эластомеры, имеющие блочную структуру: -[-Rf - H1 - H2 - H1 - ]-, где Rf-перфторполиоксиалкиленовая последовательность общей формулы
-CF2O(CF2CF2O)m-(CF2O)n-CF2-
где m/n=0,25-5, H1 и H2, одинаковые или отличающиеся друг от друга, являются бивалентными радикалами, имеющими структуру арилена, алкиларилена, алкилена или циклоалкилена, необязательно содержащую фтор и/или другие гетероатомы, выбираемые среди кислорода, серы, азота. Такие продукты получаются при использовании перфторполиоксиалкилендиола, имеющего функциональность не менее 1,97, предпочтительно, не менее 1,99, и отличаются пределом прочности на разрыв при 23°С, которая по крайней мере на 50% выше, чем предел прочности на разрыв соответствующих полимеров, полученных из перфторполиоксиалкилендиолов, имеющих функциональность не выше 1,96.
