Abstract

Official abstract text for this publication.

The present invention relates to a process for preparing high-functionality polyetherols by reacting at least one trifunctional or higher-functionality alcohol and if appropriate further di- and/or monofunctional alcohols and/or modifying reagents, with the aid of acidic catalysts, where the trifunctional or higher-functionality alcohol is not glycerol. The present invention further relates to high-functionality polyetherols obtainable by such a process and to the use of these high-functionality polyetherols as adhesion promoters, thixotropic agents, rheology modifiers of polymers, phase transfer reagents, micro- or nanocontainers for biologically active compounds, for example for active medical ingredients, biocides, herbicides or fungicides, as pigment dispersants, an additive in printing inks or as structural units for preparing polyaddition or polycondensation polymers or for treatment of seed.

First claim

Opening claim text (preview).

The invention claimed is: 1. A process for preparing a high-functionality polyetherol comprising reacting by polymerization, other than by ring-opening polymerization of an oxetane, at least one triol or polyol with optionally at least one of a diol, a monool and/or a modifying reagent, as the only reactants, with the aid of an acidic catalyst, wherein the modifying reagent is not the same as said monool, diol, triol and polyol, wherein the triol or polyol is at least one compou…
