| titleOfInvention | High-density polyethylene |
| abstract | FIELD: chemistry. ^ SUBSTANCE: invention describes multimodal polyethylene which is suitable for use as a film, as well as a pipe. The polyethylene is characterised by density between 0.940 and 0.965 g/cm3, flow melt index l21 between 4 and 20 dg/min. The polyethylene contains a low-molecular ethylene copolymer, having weight-average molecular weight between 5000 and 50000 amu, characterised by short-chain branching index between 2.5 and 4.5; and high-molecular ethylene copolymer, having weight-average molecular weight between 60000 and 800000 amu, characterised by short-chain branching index between 2 and 2.5. The invention also describes multimodal polyethylene, where the weight ratio of the high-molecular ethylene copolymer in terms of the overall multimodal composition is between 0.3 and 0.7. The ratio of branching indices of the low- and high-molecular ethylene copolymers is between 1.2 and 6.0. ^ EFFECT: balance of short-chain branches makes multimodal polyethylene suitable for use in making films, pipes, in fields using centrifugal moulding and blow moulding. ^ 23 cl, 5 dwg, 6 tbl, 4 ex |
