FIELD: chemistry. n SUBSTANCE: invention relates to a structure based on polyethylene, containing a polymer composition containing 60–90 wt% polyethylene (A), 5–35 wt% acid-modified polyethylene (B) and 5–35 wt% meta-xylylene group-containing polyamide (C), where meta-xylylene group-containing polyamide (C) is dispersed in form of layers in structure, and acid number of acid-modified polyethylene (B) has a value from 10 to 30 mg/g. n EFFECT: structures based on polyethylene have excellent barrier properties with respect to fuel materials and chemicals, as well as with respect to different gaseous substances, such as oxygen, and also exhibit strength suitable for practical application. n 6 cl, 2 dwg, 1 tbl |
