ROTOMOLDING COMPOSITION

A polyethylene composition suitable for rotomolding and comprising a blend of a stabilized polyethylene, and optionally a substantially non-stabilized polyethylene, with a recycled polymer (PCR), is described. By using a PCR with a higher density and lower melt flow as compared to the stabilized polyethylene, a higher portion of the recycled polymer is present on the interior surface f the rotomolded part. Oxidation of the recycled polymer results in formation of oxidized species, such as carbonyl groups, on the interior surface of the part, which along with higher surface roughness enhances adhesion between the interior surface and coatings or fillings, such as polyurethane, used to provide a layer of insulation or improve structural strength or buoyancy.
