Abstract:
The present invention relates to the preparation of hyperbranched polyamines and its use to exfoliate inorganic clays into random form of nanosilicate platelets. The hyperbranched polyamines serving as exfoliating agent are prepared by polymerizing poly(oxypropylene)-triamine and diglycidyl ether of bisphenol-A (DGEBA). Hydrophilic amine groups of the exfoliating agent are acidified and then reacted with the layered inorganic silicate clay through cation exchange reaction and physical clay exfoliation to give random form of nanosilicate platelets.
