1. A polymer blend comprising two or more immiscible polymers and a compatibilizer comprising a plurality of polymer backbones cross-linked by cross-links that are Diels-Alder reaction products of at least one dienophile-containing moiety and at least one diene-containing moiety, wherein the compatibilizer is melt blended into the two or more immiscible polymers.
