POLYETHYLENE COMPOSITION FOR PRODUCTS FROM STRETCHED BELT Russian patent published in 2011 - IPC B32B27/32 C08L23/06 D01D5/42 D01F6/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a novel polyethylene composition which is particularly suitable for making monothreads, monobelts and a stretched belt. The invention also relates to a film containing said composition, as well as use of the polyethylene composition to obtain textile articles made from fibre, monobelts or stretched belts. The composition contains 95.1-99.5 wt % polyethylene and 4.9-0.5 wt % polybutene. The polyethylene is a homopolymer or copolymer of ethylene, having density higher than 0.930 g/cm³, polydispersity M_w/M_n from 2.0 to 5.9 and MFR (190/5) from 1.5 g/10 min to 5.0 g/10 min. The polybutene is a homopolymeer of 1-polybutene or a copolymer of butene, and the polybutene has MFR (190/5) from 1 g/10 min to 10 g/10 min. The composition is used to obtain a film. The invention also describes use of the polyethylene composition to produce monothreads, monobelts or stretched belts, and a method of producing a stretched belt from the polyethylene composition.

EFFECT: stability of the sleeve and mechanical properties of films made from said composition are greatly improved.
