ADHESIVE POLYETHYLENE COMPOSITION Russian patent published in 2024 - IPC C09J151/06 C09J123/08 C08L51/06 B32B27/32 B32B7/12 

FIELD: polymers.

SUBSTANCE: polyethylene adhesive composition suitable for multi-layer structures. The specified composition contains (A) from 60 to 90 wt.% non-elastomeric polyethylene, which is a ternary copolymer of ethylene with two different alpha-olefin comonomer units having from 4 to 12 carbon atoms and (B) from 9.0 to 38 wt.% elastomer. Component (A) or components (A) and (B) are grafted with an acid grafting agent (C) in an amount of 0.01 to 3.0 wt.%, all based on the total weight of the adhesive polyethylene composition.

EFFECT: resulting adhesive compositions improve the peel strength of coatings subjected to reduced water cooling times.
