Abstract

The present invention provides for a polyolefin-based composition made from or comprising (A) a first polymer composition made from, or containing an ethylene polymer grafted with an unsaturated monomer, and (B) a second polymer composition comprising a propylene polymer, wherein the ethylene polymer grafted with an unsaturated monomer is covalently bonded to the propylene polymer. The polymeric composition may be used as a tie-layer adhesive composition.

Description

[0001] Cross References to Related Applications [0002] This application, filed under the Patent Cooperation Treaty, claims the benefit of priority of US Provisional Application No. 62 / 278,145, filed January 13, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] Generally, the present disclosure relates to polyolefin-based compositions useful as adhesives, tie layer adhesives for multilayer structures, and compatibilizers. Background technique [0004] Tie layer adhesives can be used to bond polyolefins to different substrates in multilayer, coextruded structures used in beverage and food containers (e.g. bags, shrink bags, pouches, boxes, trays , covered trays, wrap-around trays, form shrink wrap, vacuum sticker packs, flow wrap packs, thermoformed packs, pack inserts, or combinations thereof), pharmaceutical and cosmetic containers, shipping packs, electronic components, synthetic fibers, fiber stuffing materials application...
