FIELD: process engineering.SUBSTANCE: invention relates to production of films from superhigh-molecular polyolefin. Proposed method comprises affecting initial superhigh-molecular polyolefin with weighted mean molecular weight of, at leas 500000 g/mol in the form of compacted powder by isobaric press. Besides, compacted polyolefin of rolling stage is subjected to definite processing. Also, it is stretched at such conditions whereat polymer processing temperature does no up to magnitude exceeding its fusion point at no point whatsoever.EFFECT: high-quality films from superhigh-molecular polyolefin.15 cl, 2 dwg |
