Abstract
Polymeric composites may be produced by a process comprising melt-kneading an organophilic clay and a polymer at an average reduced pressure of at 5×10 Pa, a maximum reduced pressure of at least 1×10 Pa, and a total shear strain between 10 and 10 , and/or a total shear energy per unit volume falling between 10 and 10 Pa. Polymeric composites produced under these conditions may have 50% or more of the entire layers of the layered organophilic clay dispersed as monolayers.
