Abstract

There is provided a polymeric material comprising: a co-continuous or highly-continuous blend of polyethylene and polypropylene, the blend comprising a polyethylene phase and a polypropylene phase separated by a polyethylene/polypropylene interface; and one or more thermoplastics other than polyethylene and polypropylene, the one or more thermoplastics each having an interfacial tension with polypropylene higher than the interfacial tension of the polyethylene/polypropylene interface, wherein the one or more thermoplastics form discrete phases that are encapsulating each other, and wherein said discrete phases are comprised within the polypropylene phase of the co-continuous or highly-continuous blend or are located at the polyethylene/polypropylene interface. There is also provided a process for recycling a blend of thermoplastics comprising polyethylene, polypropylene and one or more other thermoplastics, the process comprising the step of melting and mixing the polyethylene, the polypropylene and the one or more other thermoplastics, thereby producing a polymeric material.
