the present invention discloses a complex of clay and polyoxyalkylene amine grafted polypropylene and a method for producing the same . the clay in the present invention is formed by modifying inorganic layered silicate clay with an amphibious intercalating agent obtained by polymerizing polyoxyalkylene amine having molecular weight over 1 , 800 and polypropylene - grafting - maleic anhydride . the method for producing the complex is primarily to polymerize the polyoxyalkylene diamine having molecular weight over 1 , 800 and polypropylene - grafting - maleic anhydride to form an amphibious intercalating agent , which is then acidified with an inorganic acid , and mixed with the swelled clay by powerfully stirring at 60 - 80 ° c . for cation exchanging to obtain the titled complex . according to the present invention , the complex is an excellent surfactant and a reinforcing agent of polymers .
