IMPROVED RESIN COMPOSITIONS FOR COATINGS APPLIED BY EXTRUSION Russian patent published in 2017 - IPC C08L23/08 C08L23/06 C09D123/06 

FIELD: chemistry.

SUBSTANCE: composition comprises 50 to 90 wt % of the first polyethylene component, 1 to 10 wt % of the second polyethylene component and 10 to 50 wt % of the third polyethylene component. Moreover, the first polyethylene component in the composition includes low density linear polyethylene with density ranging from 0.90 g/cm³ to 0.96 g/cm³ and melt index (I₂) from 5 to 15 g/10 min, the second polyethylene component includes high-pressure low density polyethylene with density ranging from 0.915 g/cm³ to 0.930 g/cm³ and melt index (I₂) from 0.1 g/10 min to 3 g/10 min and the third polyethylene component includes high-pressure low-density polyethylene with density ranging from 0.915 to 0.930 g/cm³and melt index (I₂) from 5 to 15 g/10 minutes.

EFFECT: composition according to the invention exhibits low restriction and superior resistance to stretching.
