Abstract: Chain-extended nanonylon is made from the reaction of oligomeric nanonylon and chain-extending agents. Such chain-extended nanonylon contains concentrations of organoclay exceeding 10 weight percent. High concentrations of organoclay permit the chain-extended nanonylon to be used as either a concentrate or a compound that provides good barrier properties for thermoplastic articles made from the chain-extended nanonylon.

Abstract: A thermoplastic composition is disclosed comprising a continuous phase of at least one thermoplastic polymer; and a non-polymeric precursor polymerizable to provide a polymerized reinforcing phase dispersed within the thermoplastic polymer. The precursor is polymerized after dispersion into the continuous phase of thermoplastic polymer. The flexural modulus of the thermoplastic polymer is thereby increased. Methods of making and using the composition are also disclosed.

Abstract: A cathodic protection polymeric compound is disclosed. The compound has flowable material to serve as a binder, carbonaceous conductive media dispersed in the flowable material, sacrificial metal particles also dispersed in the flowable material. The carbonaceous conductive media serve as a carbon-based electron transfer agent and are in the form of particles, platelets, fibers, tubes, or combinations thereof. A galvanic circuit is formed by the metal particles serving as anodes, a metal substrate to be protected serving as the cathode, and the conductive media serving as the electron transfer agent. The flowable material can also include an ionically conductive or an inherently conductive polymer to further enhance the galvanic circuit.

Abstract: A blend of nanocomposites is disclosed, with a polyolefin nanocomposite preferably serving as a continuous phase and a polyamide nanocomposite preferably serving as a discontinuous phase.
