This invention relates to a process for the preparation of highly-branched polyols by polymerisation of glycidol in the presence of a hydrogen-active starter compound with basic catalysis, wherein glycidol is added in dilute solution and the solvent used for the dilution is continuously distilled off. The polyols thus prepared are colorless, contain as the core unit solely the starter compound used and have polydispersities of less than 1.7. The present invention also relates to polyols that comprise the reaction product of the polyols based on glycidol with one or more expoxide monomers. This invention also relates to a process for the preparation of these polyols.

A filler mixture comprising an organophilic layer silicate obtainable by treatment of a natural or synthetic layer silicate with a swelling agent selected from sulfonium, phosphonium and ammonium compounds (salts of melamine compounds and cyclic amidine compounds being excluded as ammonium compounds) and a mineral filler different therefrom, yields, in combination with thermosetting resins, nanocomposites having improved mechanical properties.

Filler mixtures

Polycyclic addition polymers derived from norbornene-type monomers are mixed with a variety of other polymers to generate families of new blends, alloys, and block copolymers.
