Abstract: Endblocked polysiloxanes with lateral amino functions and at least one further lateral and/or terminal functional group.

Abstract: The invention relates to polysiloxane block copolymers of the formula A[LB(S)Q]m, where A is a polysiloxane block, L is a divalent organic linker, B is a polymer block composed of radically polymerizable monomers, S is a sulfur atom and Q is a monovalent organic radical and m is an integer from 1 to 50, to a method for their production, and to their use in cosmetics or personal care.

Abstract: Nitrogen-containing organosilicon graft copolymers of polyalkylene oxide containing siloxane derivatives and their use.

Abstract: The invention relates to block copolymers produced by means of controlled polymerization and that have at least one block A or B comprising (meth)acrylate monomers and copolymerizable monomers, and a block P on the basis of functionalized polymers.

Abstract: The invention relates to block copolymers of the formula E-[AB]-T, where E is an initiator fragment of a polymerization initiator capable of initiating a free-radical atom-transfer polymerization reaction, A and B are differently structured polymer blocks, and T is a chain-polymer-termination group, and also to production of these and use as dispersing agent.

Abstract: The present invention relates to a process for the coammoximation, that is to say for the simultaneous ammoximation, of ketones, in particular of cyclic ketones such as cyclododecanone and cyclohexanone. Ammoximation is taken to mean here the preparation of oximes from ketones or aldehydes together with hydrogen peroxide and ammonia and in the presence of a catalyst which essentially consists of silicon, titanium and oxygen, for example titanium silicalite.

Abstract: The present invention relates to the preparation of trimethylcyclododecatriene in a continuous or batchwise process by trimerizing isoprene in the presence of a catalyst system and of a solvent. It is possible to isolate the resulting crude trimethylcyclododecatriene by means of distillation. The dimethylcyclooctadiene formed as a by-product may likewise be isolated from the crude product.

Abstract: The invention relates to polysiloxane block copolymers of the formula A[LB(S)Q]m, where A is a polysiloxane block, L is a divalent organic linker, B is a polymer block composed of radically polymerizable monomers, S is a sulfur atom and Q is a monovalent organic radical and m is an integer from 1 to 50, to a method for their production, and to their use in cosmetics or personal care.

Abstract: The present invention relates to compositions having organosilicon compounds for generating foams, where the organosilicon compounds have sulphonate groups and Si—O—C linkages, and also to the use of these compositions for producing aqueous foams, in particular fire-extinguishing foams and cleaning foams.

Abstract: The invention relates to a method for the coammoxidation, i.e. for the simultaneous ammoxidation of ketones, especially of cyclic ketones such as cyclododecanone and cyclohexanone. The ammoxidatian method of the invention relates to the production of oximes from ketones or aldehydes using hydrogen peroxide and amnmonia and further using a catalyst that substantially consists of silicon, titanium and oxygen, such as for example titanium silicalite.
