Abstract: Water-insoluble substances, for example (1) antimony oxide or (2) colloidal silica may be emulsified in water with a condensation compound obtained by reaction of an aliphatic or aromatic compound containing epoxy groups and ether linkages and an aliphatic, cycloaliphatic or heterocyclic di- or poly-amine, or a neutralized or acidified derivative of such a compound. Antimony oxide (1) may be emulsified together with chlorinated paraffin in an acidified solution of a condensation compound of a glycidyl ether of 4,41-dihydroxydiphenyl propane with ethylene diamine.  Colloidal silica (2) may be incorporated into an acidified aqueous solution of the same condensation compound, and an aqueous solution of methylol melamine etherified with methyl alcohol may be incorporated into the emulsion.ALSO:Water-insoluble compounds, for example organopolysiloxanes or cellulose ethers or esters, may be emulsified in water with a condensation compound obtained by the reaction of an aliphatic or aromatic compound containing epoxy groups and ether linkages and an aliphatic, cycloaliphatic or heterocyclic di- or polyamine or a neutralized or acidified derivative of such a compound.  Examples relate to dispersion of (3) dimethyl siloxane/perchlorethylene; (4) silicone rubber/white spirit; (5) a copolymer of hydrogen-siloxane and ethyl-siloxane/methylene chloride; (7) acetyl cellulose/methyl cyclohexanone; (9) hydrogen-polysiloxane/perchlorethylene; (10) a copolymer of hydrogen siloxane and methyl siloxane/trichlorethylene; (16) hydrogen siloxane/toluene.ALSO:Fibrous materials are finished by impregnation with an aqueous emulsion of an organic or inorganic water-insoluble substance prepared by emulsifying the substance with a condensation compound obtained by reacting an aliphatic or aromatic compound containing epoxy groups and ether linkages with an aliphatic, cycloaliphatic or heterocyclic di-on poly-amine, or a neutralised or acidified derivative of the condensation compound.  The condensation compound may be reacted with a C1 to C3 aliphatic aldehyde.  Examples refer to (1) waterproofing textiles using an emulsion of paraffin and perchlorethylene emulsified with the reaction product of 4, 4\sv dihydroxydiphenyl propane and ethylene diamine (2) water-proofing textiles using an emulsion of paraffin and Montan wax acid emulsified with the reaction product of Example (1) optionally with methylol amidazolidone and zirconium acetate added.  (8) rot-proofing organic materials using an acidified water-toluene emulsion of pentachlorophenyl lauric acid ester emulsified with an ethylene glycol glycidyl ether/N-amino ethyl piperazine product (11) flame-proofing fibre materials using a water/acetic acid/chlorinated paraffin emulsion prepared using an ethylene glycol glycidyl ether/diethylene triamine condensation product (14) oil-proofing paper using an emulsion of N-ethylamide of perfluorooctane-sulphonic acid prepared using the reaction product of resorcinol glycidyl ether and di-ethylene triamine (17) water-proofing poplin with an aqueous alcoholic emulsion of a hexamethylolmelamine etherified with methyl alcohol, and containing magnesium chloride, using as emulsifying agent the reaction product of a glycidyl ether of 4, 4\sv dihydroxy diphenylpropane with ethylene diamine.  (18) Water-proofing a polyester/cotton fabric with an aqueous acidic emulsion of a hydrogen siloxane in toluene emulsified with a glycidyl ether/ethylene diamine/formaldehyde product (19) imparting wash-proof non-slip properties to rayon taffeta using a dispersion of silica emulsified with the reaction product of a glycidyl ether of 4. 4\sv dihydroxy diphenyl-propane with ethylene diamine and subsequently mixed with an aqueous acid solution of methylol-melamine etherified with methyl alcohol.ALSO:An aqueous emulsion of an organic or inorganic water-insoluble substance is prepared by emulsifying the substance in the presence of water with a condensation compound obtained by reaction of an aliphatic or aromatic compound containing epoxy groups and ether linkages and an aliphatic, cyclo-aliphatic or heterocyclic di- or poly-amine, or a neutralised or acidified derivative of such a condensation compound.  The emulsion may contain 2% to 10% by weight of the condensation compound.  The condensation products may be further reacted with a C1 to C3 aliphatic aldehyde, for example formaldehyde, acetaldehyde, crotonaldehyde or glyoxal.  Substances emulsified are organopolysiloxanes, saponifiabe fats, oils and waxes, and their free acids; paraffin hydrocarbons; chlorinated paraffins; chlorinated rubber; pentachlorophenol esters of higher carboxylic acids; polyethylene; water-insoluble cellulose ethers or esters; polyvinyl alcohols and their esters; polyvinyl chloride; polyacrylic acids or their esters; fluorinated compounds; organic or inorganic pigments.  Examples refer to emulsification of (1), paraffin-perchlorethylene; (2), paraffin-Montan wax acid with addition of methylol amidazolidine and zirconium acetate; (3), dimethyl siloxane-perchlorethylene; (4), silicone rubber; (5), (hydrogen-siloxane and ethyl-siloxane)-methylene chloride; (6), methyl polyacrylate-benzene; (7), acetyl cellulose-methyl cyclohexanone; (8), pentachlorophenyl lauric acid ester-toluene; (9), hydrogen polysiloxaneperchlorethylene; (10), (copolymer of hydrogen-siloxane and methyl siloxane)-trichlorethylene; (11), chlorinated paraffin; (12), chlorinated paraffin-antimony oxide; (13), paraffin-polyethylene wax; (14), N-ethylamide of perfluoroctanesulphonic acid; (15), linseed oil; (16), hydrogen siloxane-toluene; (17), hexamethylol melamine etherified with methyl alcohol-magnesium chloride; (19), silica with added methylol melamine etherified with methyl alcohol.
