1. Полипропиленовые трубы, включающие, по меньшей мере, один слой, полученный из композиции пропиленовых полимеров, имеющей величину скорости течения расплава, равную 2 г/10 мин или менее, при этом композиция содержит (в массовых частях):
1) 100 частей кристаллического статистического сополимера пропилена с 1-15% (мас.) С4-С10 α-олефина либо кристаллического статистического сополимера пропилена с 1-15% (мас.) С4-С10 α-олефина и с 1-7% (мас.) этилена, получаемых путем полимеризации мономеров в одну стадию полимеризации либо в две или более последовательные стадии полимеризации или путем смешивания продуктов двух или более независимых стадий полимеризации, при этом полимерный продукт каждой стадии всегда содержит не менее 2% (мас.) звеньев сомономера (сомономеров) (а именно, этилена и/или С4-С10 α-олефина);
2) от 0 до 70 частей эластомерного полиолефина, выбираемого из группы, состоящей из
а) сополимера этилена с пропиленом и необязательно диеном, имеющего содержание этилена в диапазоне от 17 до 45% (мас.) и содержание пропилена в диапазоне от 55 до 83% (мас.);
b) сополимера этилена с С3-С10 α-олефином, с массовым соотношением этилен/С3-С10 α-олефин в диапазоне от 29 до 86% (мас.) (анализ по методу 13С ЯМР) и с соотношением Mw/Mn, меньшим 3,5; и
