CA 2713331

The invention relates to a method for producing highly functional polyetherols by reacting at least one trifunctional or higher functional alcohol and optionally further difunctional and/or monofunctional alcohols and/or modifying reagents with the help of acidic catalysts, the trifunctional or higher functional alcohol not being glycerol. The invention further relates to highly functional polyetherols that can be obtained by said method and to the use of said highly functional polyetherols as adhesion promoters, thixotropic agents, rheology modifiers of polymers, phase transfer reagents, microcontainers or nanocontainers for biolo-gically active substances, for example for medical active substances, biocides, herbicides or fungicides, as pigment dispersants, additives in printing inks, as components for producing polyaddition or polycondensation polymers or for treating seeds.

La présente invention concerne un procédé de production de polyéthérols hautement fonctionnels, dans lequel on convertit au moins un alcool tri-fonctionnel ou d'une fonctionnalité supérieure et éventuellement, d'autres alcools di- et/ou monofonctionnels et/ou des réactifs de modification à l'aide de catalyseurs acides, l'alcool tri-fonctionnel ou d'une fonctionnalité supérieure n'étant pas la glycérine. La présente invention concerne en outre des polyéthérols hautement fonctionnels, pouvant être obtenus selon ce procédé et l'utilisation de ces polyéthérols hautement fonctionnels en tant qu'agents adhésifs, agents thixotropes, modificateurs de la rhéologie de polymères, réactifs de transfert de phase, micro- ou nano-conteneurs d'une substance biologiquement active, par exemple, un principe actif médical, des biocides, herbicides ou fongicides, comme agents de dispersion de pigment, additif d'encres d'imprimerie, éléments de production de polymères par poly-addition ou polycondensation ou pour le traitement de graines.
