<p>Multilayer complex comprises a polypropylene-based first layer, a polyethylene-based core layer, and a polypropylene-based second layer. The core layer comprises: 40-100 (preferably 70-100) % of ethylene copolymer and alpha -olefin (I); 0-50 (preferably 10-20) % of high density polyethylene; and 0-50 (preferably 20-30) % of low density polyethylene. Multilayer complex comprises a polypropylene-based first layer, a polyethylene-based core layer, and a polypropylene-based second layer. The core layer comprises: 40-100 (preferably 70-100) % of ethylene copolymer and alpha -olefin of formula (CH 2=CH-C nH 2 n + 1) (I); 0-50 (preferably 10-20) % of high density polyethylene; and 0-50 (preferably 20-30) % of low density polyethylene. n : 2-10. An independent claim is included for preparing a multilayer complex object by blow extrusion molding.</p> |
