Abstract: A process is provided for producing a compatibilized polymeric blend. A first thermoplastic polymer and a reactive moiety are provided to a progressive melt kneading apparatus. The reactive moiety comprises a first reactive group capable of reacting with the first thermoplastic polymer but not a second polymer and a second reactive group capable of reacting with the second polymer but not the first polymer. The first thermoplastic polymer and the reactive moiety are then melt kneaded so that the first reactive group reacts with the first thermoplastic polymer and the second reactive group is grafted to the first thermoplastic polymer, forming a molten self-compatibilizer. A molten second polymer is then provided. The molten self-compatibilizer is melt kneaded with the molten second polymer so that the second reactive group reacts with the second polymer to form a compatibilized polymeric blend. Also provided are articles formed from the compatibilized polymer blend.
