Abstract

See full text

A multilayer article prepared by rotational moulding can include a layer A that is a polyolefin (PO) based layer prepared from PO and a functionalised polyolefin (FPO), or a PO grafter to a non-polyolefin (NPO) in the form of a block copolymer (PO-g-NPO). A layer B can be a PO that is dissimilar from layer A, an NPO, a mixture thereof, and optionally an FPO or a PO-g-NPO. A layer C can be dissimilar from layer A and similar to or dissimilar from layer B. Layer C can be adjacent to layer A and/or layer B, can have good adhesion to layer A and/or layer B, and is not a blend of layer A and layer B.
