Abstract

The invention relates to novel hybrid compounds comprising at least one polyol entity (Po) - for example oligomer or polymer - in which at least one of the hydroxyl functions of Po is substituted by at least one entity A that can be of a variable nature, for example polymer (e.g. polyorganosiloxane-POS), hydrocarbonated or mineral. The bond Ro between the entity Po and the entity A is obtained by means of ''click chemistry'' and corresponds to formula (II.1) or (II.2), Z representing -CH- or -N-. A is an entity selected from the group comprising the various polyols of Po, polyorganosiloxanes (POS), polyalkylene glycols, polyamides, polyesters, polystyrenes, alkyls, alkenyls, alkynyls, aryls, and combinations thereof, in addition to mineral materials such as silica and the combinations thereof. Said hybrid components can be used as emulsifiers, esepcially for cosmetics.

Description

technical field [0001] The present invention relates to novel hybrid structures comprising at least one organosilicon entity- Sil - (e.g. polymer: e.g. polysiloxane-POS) and at least one entity B , the entity B Can be of various properties: hydrocarbons or inorganic substances, such as oligomers or polymers, especially polyols (Po). Available in entities- Sil and entity B One or more linkages between azide (or nitride) active units react with alkyne or nitrile active units to form triazole or tetrazole type linking hinges (linking hinge) (Ro ). [0002] The invention also relates to methods for obtaining these hybrid structures and their use, for example as amphiphilic compounds. [0003] Finally, the invention also relates to synthons, ie functional groups bearing azide and / or alkynyl and / or nitrile groups, as well as intermediate products involved in the preparation of hybrid structures. Background technique [0004] entity Sil Silicone refers especially to POS pol...
