POLYOLEFIN-BASED COMPOSITIONS, ADHESIVES AND OBTAINED MULTILAYER STRUCTURES Russian patent published in 2020 - IPC C08L23/12 C08L23/16 C08L51/06 B32B27/32 C09J151/06 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions based on polyolefin, used as adhesive substances, adhesive substance compounds of an adhesive layer for multilayer structures and additives which improve compatibility. Disclosed polyolefin-based composition used as an adhesive, containing a first polymer composition comprising an ethylene polymer grafted with maleic acid anhydride; and a second polymer composition containing a copolymer of impact-resistant polypropylene, in which an ethylene polymer, grafted with maleic anhydride, is covalently bonded to a copolymer of impact-resistant polypropylene, as well as multilayer structure containing glue layer adhesive substance, a polymer layer, a substrate layer.

EFFECT: technical result is obtaining a polymer composition used as adhesive substance of adhesive layer.
