摘要： An aqueous siloxane resin containing emulsion is prepared by: (i) adding water, at least one nonionic surfactant, optionally adding an ionic surfactant, and a catalyst, to a reaction vessel, and heating the contents of the vessel to form a mixture; (ii) adding to the mixture at least one silane monomer of the formula RSi(OR′)3; (iii) optionally, adding to the mixture, silane monomers of the formula R2Si(OR′)2 or R3SiOR′; (iv) allowing the silane monomer to hydrolyze and condense by a polymerization reaction in the catalyzed aqueous mixture; (v) terminating the reaction by neutralizing the mixture; and (vi) recovering from the mixture a siloxane resin emulsion containing a siloxane resin.
