An improved process for preparing ester containing organosilicon compounds by reacting chloro-organosilicon compounds with a carboxylic acid in the presence of a base and a promoting solvent, the improvement which comprises conducting the reaction in the presence of a halide salt.

Preparing ester containing organosilicon compounds

Organopolysiloxane fluids are stabilized against degradation in the presence of kaolin clays at elevated temperatures by adding an amine containing compound to the organopolysiloxane fluids.

Radiation polymerizable acrylate-functional organopolysiloxanes having the formula ##STR1## where R is a radical selected from monovalent hydrocarbon radicals, substituted monovalent hydrocarbon radicals having from 1 to 20 carbon atoms or monovalent hydrocarbonoxy radicals having from 1 to 20 carbon atoms, or a radical of the formula ##STR2## in which at least one R is a radical having the above formula, R.sup.1 is a divalent radical selected from a saturated divalent hydrocarbon radical having up to 20 carbon atoms, a divalent hydrocarbonoxy radical in which the oxygen is in the form of an ether linkage and an unsaturated divalent hydrocarbon radical having from 3 to 10 carbon atoms; R.sup.2 is hydrogen or a methyl radical; R.sup.3 is a linear or branched radical having 2, 3, 4, 5 or 6 valences in which the radical is selected from a substituted hydrocarbon radical, or a hydrocarbon ether or thioether radical having one or more repeating units and the terminal atoms of the R.sup.3 radical are selected from oxygen or nitrogen; R.sup.4 is a radical linked to the terminal oxygen or nitrogen atoms of R.sup.3 and is selected from the group consisting of a monovalent hydrocarbon radical having from 1 to 20 carbon atoms, an acryloyl radical, and a substituted acryloyl radical and when the terminal atom of R.sup.3 is oxygen, then R.sup.4 may also be hydrogen. R.sup.5 is a monovalent hydrocarbon radical having from 1 to 20 carbon atoms or a radical of the formula

Acrylate-functional organopolysiloxanes

Thiofunctional polysiloxane fluids are stabilized against degradation in the presence of kaolin clay by adding an amine containing compound to the thiofunctional polysiloxane fluids.

Stabilized thiofunctional polysiloxane fluids and a process for

A textile finishing composition comprising (1) a diluent and (2) a durable press resin composition containing (a) an aminoplast resin and (b) an aldehyde. The textile finishing composition is combined with an acid catalyst and applied to textile materials to impart softness, improved wetting properties and durable press properties. The textile finishing composition is applied at lower than normal dry add-on levels to textile materials to provide textile materials having lower levels of formaldehyde.
