摘要：

Amphilic copolymer P(TDI-DMPA) (PU) with carboxy group was synthesized using TDI and DMPA as monomers. Then the organic-inorganic composite CaCO3/PU was prepared via in-situ precipitation method. When the concentration of PU is 80 g/L and the loading concentration of CaCO3 is 4 X 10(-2) mol/L, the CaCO3 particles in the as-obtained film are of uniform size and good dispersion. XRD test was carried out to determine the crystal structure of the calcium carbonate. It was revealed by IR analysis that the interaction of PU and CaCO3 in the composite was chemical adsorption and coordination. This method can greatly improve the joining intensity of CaCO3 and PU, which provides a good idea for the preparation of inorganic/organic composites.
