Abstract:
A method for producing a polymeric composite material comprising:melt-kneading an organophilic clay and a polymer so that the average value (Pâ€²ave) and the maximum value (Pâ€²max) of a reduced pressure on a kneaded material comprising the organophilic clay and polymer at one or more loading regions in a kneader are within the ranges shown below and that a total shear strain (A) and/or a total shear energy per unit volume (E) in all loading regions of the kneaded material are within the ranges of â€ƒPâ€²ave&gE;5Ã—104(Pa),Pâ€²max&gE;1Ã—105(Pa), 105&lE;A&lE;107, and 1010(Pa)&lE;E&lE;1014(Pa). wherein 50% or more of the entire layers of the layered organophilic clay are dispersed as monolayers.
