POLYOLEFIN-BASED FORMULATIONS, ADHESIVES AND RESULTING MULTILAYER STRUCTURES Russian patent published in 2018 - IPC C09J123/06 C08L23/06 C08L23/22 C08L51/06 B32B27/32 

FIELD: glutinous industry.

SUBSTANCE: group of inventions relates to glutinous industry. Adhesive composition based on polyolefin contains: (A) first polymer composition, including polyolefin grafted onto unsaturated monomer; (B) second polymer composition comprising polyethylene; (C) third polymer composition comprising: (i) first polyisobutylene and (ii) second polyisobutylene. First polyisobutylene has a viscosity average molecular weight (VAMW₁), and second polyisobutylene has viscosity average molecular weight (VAMW₂), wherein VAMW₁ ≠ VAMW₂. Adhesive composition based on polyolefin is used for a layer for multilayer structures. Composition is used as an adhesive to glue the metal layer.

EFFECT: increase in adhesion of the adhesive composition to metals is provided.
