A lubricant for a substrate, particularly a synthetic material, comprising a hydrogen polyorganosiloxane having the structure ##STR1## in which R is an alkyl radical containing up to 14 C atoms or a halogen- or pseudohalogen-substituted low molecular weight alkyl radical or a phenyl radical, with the proviso that at least 50% of all the R radicals consist of methyl groups; R.sub.1 is a methyl radical; n is a number from 0 to 15; x is a number from 100 to 1000 and y is a number from 2 to 10. The lubricant is particularly useful in a method to lubricate artificial turf such as the type used on football, soccer and baseball fields.

Lubricant based on polyorganosiloxanes

Ketene dimers of the general formula ##STR1## wherein R.sub.1 and R.sub.2 independently of one another denote an alkyl or alkenyl radical each of which has at least 8 C atoms, a cycloalkyl radical having at least 6 C atoms or an aryl or aralkyl radical are used for the treatment of wool and synthetic polyamide fibres.

Treatment of polyamide fibres

Aqueous dispersions of copolymers and graft copolymers which are formed from ethylenically unsaturated perfluoroalkyl monomers and ethylenically unsaturated monomers from from perfluoroalkyl groups and which are prepared in the presence of emulsifiers containing cationic groups are used for imparting a water-repellent and oleo-repellent finish to textiles, leather and paper.

Copolymers containing perfluoroalkyl groups

The present invention relates to graft copolymers based on at least one ethylenically unsaturated monomer containing perfluoroalkyl groups mixed with an acrylic, methacrylic, vinyl, maleic and/or styrene derivative and a melamine polycondensate as the graft substrate, which are suitable for oleophobic treatment of textiles, carpets, paper or leather and at the same time are effective hydrophobicity agents, and a process for their preparation.

Graft copolymers, a process for their preparation and their use

Waterproofing and oil-proofing agents contain A. compounds containing a perfluoroalkyl group, and B. quaternization products of basic fatty acid amides.

A graft polymer dispersion suitable for finishing textiles and comprising water, a dispersing auxiliary and a polymeric product produced by subjecting to free radical polymerization a composition comprising

Graft-modified siloxane dispersions for finishing textile materials

Imidazoline derivatives of the formula ##STR1## in which R.sub.1, R.sub.2 and R.sub.3 designate C.sub.1 -C.sub.19 -alkyl or C.sub.2 -C.sub.19 -alkenyl,

Textile-treatment agents, and their use for finishing textile materials

A de-foaming agent comprising by weight about

Continuous dyeing and simultaneous finishing of textile materials using

A textile pile-stabilizing impregnating agent comprising a colloidal suspension of silicic acid having SiO.sub.2 units and organosilsesquioxanes having units of the formula RSiO.sub.3/2 wherein R is an alkyl or aryl radical with up to 7 carbon atoms. It is produced by adding a silane of the formula RSi(OR').sub.3, together with a silane of the formula Si(OR').sub.4, wherein R is an alkyl or aryl radical with up to 7 carbon atoms, and R' is a hydrogen atom or an alkyl radical with 1 to 4 carbon atoms, to a mixture of water and a surface-active agent containing a buffer, the amount of silanes added being about 5 to 22% of the total weight of the addition plus mixture.
