Without solvent, a series of water-based fluorosilicone polymers were synthesized from allyl polyoxyethylene polyoxypropylene ether, organic fluoride and poly(methylhydrosiloxane) via hydrosilylation, and the aqueous dispersions of the polymers were obtained by the way of emulsification. Then the structures and properties of the samples were analyzed by FTIR,1H NMR and TEM. The surface tension of the aqueous dispersions at 2.0 wt% fell to 22.00～26.00 N/m, to behave shear thickening. The size and form of the particles of such aqueous dispersions are obviously different.

Key words: fluorosilicone, hydrosilylation, poly(methylhydrosiloxane), aqueous dispersion
