## Abstract Solidβstate polymerization (SSP) of a poly(hexamethyleneadipamide) (PA 6.6)/clay nanocomposite system was studied. SSP runs were performed in a fixedβbed reactor, at temperatures 160β200βΒ°C and reaction times up to 8βh. The influence of clay presence on the PA 6.6 SSP rate constant was
An unsteady reaction-diffusion model has been developed to represent the polymerization of a nylon 6,6 prepolymer in a stationary film. A realistic kinetic and equilibrium description is incorporated by the use of apparent rate and equilibrium constants that are composition dependent. The model is s
