MULTILAYER STRUCTURE COMPRISING A MODIFIED IMPACT EVOH LAYER |
摘要 |
<p>The present invention relates to a multilayer structure comprising the following successive layers: a polyamide or HDPE (high-density polyethylene) layer; a tie layer; an impact-modified EVOH layer; optionally, a tie layer; and a polyamide or polyamide/polyolefin blend or polyolefin layer, the latter layer possibly containing fillers in order to make it antistatic; and such that the impact-modified EVOH layer is a blend based on EVOH and at least one modifier chosen from: a) functionalized ethylene/alkyl (meth)acrylate copolymers; b) products resulting from the reaction of (i) a copolymer of ethylene and of an unsaturated monomer X grafted or copolymerized with (ii) a polyamide; c) blends of a) and b); d) polyamides, preferably PA-6; e) blends of a) and d); f) elastomers, preferably EPR, EPDM and NBR, these elastomers possibly being functionalized; g) S-B-M triblocks; h) triblocks formed from a poly(butyl acrylate) block between two PMMA blocks; and i) linear or star S-B-S block copolymers, these optionally being hydrogenated (they are then denoted by S-EB-S).</p> |
