The present invention relates to alkoxyalkylsilane-modified polysiloxanes, to processes for the production thereof, and to the use thereof.

Alkoxyalkylsilane-modified polysiloxanes and processes for the production thereof

The present invention relates to method for improving the color index of an organopolysiloxanes functionalized with a benzalmalonate said method comprising the step of contacting said organopolysiloxanes functionalized with a benzalmalonate with a hydroxy carboxylic acid or a cyclic ester thereof in an organic solvent.

Method for improving the color index of organopolysiloxanes

The present invention relates to method for improving the color index of organopolysiloxanes functionalized with at least one UV-light absorbing group said method comprising the step of contacting said group carrying organopolysiloxanes with a hydroxy carboxylic acid or a cyclic ester thereof in an organic solvent.

The invention relates to a process for removing silicones present on fibers, yarns or textile sheet materials (substrates) wherein an aqueous preparation is allowed to act on the substrates, and then the thus treated substrates are rinsed to remove the residual silicone, characterized in that said preparation contains from 0.5 to 10% by weight of surface-active quaternary ammonium compounds and from 0.5 to 5% by weight of alkali hydroxide, respectively based on the aqueous preparation. The process is suitable, in particular, for the recovery and recycling of fibrous material and silicones from airbags or coated fabric scraps from the ready-making of airbags.

Removing the silicone coating from coated fabrics and airbags

The present invention relates to a process for the preparation of an organopolysiloxane functionalized with a benzalmalonate by hydrosilylation, said process involving the use of a hydroxy carboxylic acid or a cyclic ester thereof.

Process for the preparation of an organopolysiloxane functionalized with a benzalmalonate by hydrosilylation in the presence of a hydroxy carboxylic acid or a cyclic ester thereof

The present invention relates to a polysiloxane of the general formula (I) having at least one epoxidic radical and at least one quaternary nitrogen atom and also a textile auxiliary which comprises at least one polysiloxane according to the present invention. The polysiloxane is capable of crosslinking with or on the fiber.

Polysiloxane and textile auxiliary containing a polysiloxane

The invention relates to amido-functional aminopolydiorganosiloxanes, a method for the preparation thereof, formulations containing such amido-functional aminopolydiorganosiloxanes, and the use thereof.
