| abstract |
The present invention discloses a multi-layer article made by rotational molding, which includes: a) grafting polyolefin (PO) or a mixture thereof to 40 to 100% by weight and functionalized polyolefin (FPO) or non-polyolefin (NPO). Layer A, b) Layer A, which is a polyolefin (PO) based layer made from a composition comprising 60 to 0% by weight of PO in the form of a block copolymer (PO-g-NPO) PO or NPO or a mixture thereof different from the PO of layer B, optionally a layer B comprising FPO or (PO-g-NPO), c) optionally a polymer different from layer A and of layer B Made of the same or different polymer, located adjacent to layer A and / or layer B and when present, good adhesion to layer A and / or layer B Comprising a layer C, characterized in that not being a mixture of and layer A and the layer B indicates. The present invention also discloses a method of manufacturing such a product. |
