  • Patent number: 8026309
    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.

  • Publication number: 20110111153
    Abstract: A method for producing a high strength, flexible crosslinked polyethylene (PEX) material is provided wherein the base polymer is intermixed with a polymer modifier which affects the amorphous region of the polymer, leaving the crystalline portion of the base polymer virtually unaffected. Consequently, the amorphous region's density is lowered, resulting in a more flexible final product, while the crosslinked molecular structure and/or crystalline portion of the polymer, which controls the strength of the base polymer, remains strong. The polymer modifier can comprise a hydrocarbon fluid such as PAO, Group III basestocks, or a gas-to-liquid hydrocarbon. The plastic material has particular utility in the production of tubing, piping, and conduits for transporting gases, liquids, and the like, as well as wire and cable coatings such as jacketing and insulation.
