| Zusammenfassung: | Disclosed are polymer blends composed of from 25 to 75 wt % of ethylene homopolymer produced in a high pressure tubular reactor and from 75 to 25 wt % of ethylene homopolymer produced in a high pressure autoclave reactor, provided that each homopolymer is removed from the reaction zone prior to being blended together. The blends so formed have a good combination of neck-in and adhesion properties. A process for the extrusion coating of a substrate with these new polymer blends is also described. |
