α-Zirconium Phosphate Apply in P/S

α-Zirconium Phosphate (a-ZrP) is a kind of layered inorganics, it will still keep its layered structure when the guest is inserted into the layers and it is also a filler for the preparation of polymer/layered inorganic nanocomposites due to its high ion-exchange capacity, tunnable size and aspect ratio, and narrow size distribution. However, the high degree of erystallinity and small layer spacing have hindered the well-dispersion of α-ZrP in polymer. In order to improve the compatibility ofα-ZrP with polymers, a novel method for the preparation of organic modified α-ZrP has been presented in this paper. In this novel method, a precursor was obtained after a-ZrP was intercalated by methylamine. Then the organically-modified a-zirconium phosphate had been synthesized through ion-exchange of the methylammonium cations in the precursor with styryl quaternary ammonium ions, which had been prepared from the reaction of N, N-dimethyl octadecylamine with 4 -chloromethyl styrene.
