ABSTRACT:
A process for preparing a polyamide composite material comprising (1) contacting a layered silicate having a cation exchange capacity of 50 to 200 milliequivalents/100 g with an organic cation of a lactam which is a swelling agent in a dispersing medium, thereby obtaining a composite having the organic cation of the lactam adsorbed onto the layered silicate, and mixing the composite with a polyamide monomer; or (2) mixing a layered silicate having a cation exchange capacity of 50 to 200 milliequivalents/100 g with a compound which becomes a swelling agent through the action of an acid, a polyamide monomer and acid with pKa value of 0 to 3 in a dispersing medium. The mixture containing the polyamide monomer is polymerized to prepare the polyamide composite material.
